    SUMPRODUCT Formula, using OR Logic

    Good afternoon,

    I'm in a bit of a predicament. I only have a basic understanding of the SUMPRODUCT formula to begin with and have been using it within this training tracker for a couple months. It's just come to my attention that on the "Attendance Reports" tab, the "Attended" will only count cells that have a number >0. I would like to figure out how to have it populate based upon the cell containing either 1) a percentage or 2) the letter "A". How would I format that into the formula? Thanks!


    Here is the formula, workbook in question is attached with sensitive data redacted.

    See if this helps you out. http://www.utteraccess.com/wiki/Array_Formulas

    It's an article on array formulas but it uses SUMPRODUCT as an example of the logic.

    When using * instead of -- in SUMPRODUCT, you can think of * as AND and + as OR.

    SUMPRODUCT((Range A=B)*((Range C=1) + (Range C="A")) * (Range D))

    This gets the sum of D where Range A = B AND (Range C is either 1 OR "A")
    One spreadsheet to rule them all. One spreadsheet to find them. One spreadsheet to bring them all and at corporate, bind them.

    A picture is worth a thousand words, but a sample spreadsheet is more likely to be worked on.

    Re: SUMPRODUCT Formula, using OR Logic

    Hi, welcome to the forum

    My very first comment to you would be to try and avoid using merged cells like you have there. They cause all sorts of problems with formulas, and it is often possible to achieve the same result just by adjusting the row height and column width

    2nd, you could probably shorten that formula to this...
    =SUMPRODUCT( IF($F$28="All",1,('Training Data'!B$5:B$1497=F$28))*('Training Data'!C$5:C$1497>=F$30)*('Training Data'!C$5:C$1497<=F$32)*('Training Data'!$D$4:$CF$4=$F$34)*('Training Data'!D$3:CF$3=F$36)*(ISTEXT('Training Data'!$D$5:$CF$1497))*('Training Data'!$D$5:$CF$1497="N"))

    Im not sure which selection to use to test for what you want, but have you tried to just add another condition like you did with "N"?

    The "N" on the Attendance Reports is meant to show a No show. The only data that will trigger a count for the No Show is an "N", unlike the Attended which may or may not include a test score. Sometimes we simply need to track attendance without an assessment. Therefore, I'd require the formula to count both a number or the letter "A".

    The merged cells is something I do actively try to avoid, I'm surprised I didn't actually do as you suggested in the first place. However, I will definitely be fixing that because, as you stated, they are needlessly difficult to work with at times.

    That's is what I have gathered from my research, the bit about * being AND and + being OR... Unfortunately, it doesn't seem to want to work the way I think it should when I do it... I attempted to make it work originally using this:

    Re: SUMPRODUCT Formula, using OR Logic

    One more suggestion. Since you are using Excel 2016, you have tables. If you convert the data range to an Excel tables, you get two benefits:
    1. if you add more data at the end of the range, you do not have to adjust the formula - Tables "know" how big they are and formulas automatically adjust to reference exactly the right amount of rows.
    2. You can use column header names in the formulas. Table1[DOH] easier to remember than what $C$5:$C$1497 means.

    Here is more information on Excel Tables: http://www.utteraccess.com/wiki/Tables_in_Excel.

    Again, not which parts of your data to test this against, but Im thinking that if 1 of your arguments used COUNTA(), that may help?

    If you could indicate a (small) section of data that I could use, as well as what you expect, I could do some testing

    I'm used to seeing SUMPRODUCT applied to an nx1 array (a single column or row). I've not seen it applied to multiple rows.

    Apologies, attached is a version of the original form except everything is hidden that isn't directly relevant to my goal. The first tab displays a series of data, some "N", "A" and percentages. I am trying to find a way to have both "A" and the percentages count in the "Attended" section of the second tab.

    Thank you for your help! I apologize for being difficult.

    Re: SUMPRODUCT Formula, using OR Logic

    This appears to give the correct result


    =IF($F$28="All",SUMPRODUCT(('Training Data'!$C$5:$C$568>=F$30)*('Training Data'!$C$5:$C$568<=F$32)*('Training Data'!$D$4:$CF$4=$F$34)*('Training Data'!$D$3:$CF$3=F$36)*('Training Data'!$D$5:$CF$568>0)*('Training Data'!$D$5:$CF$568<>"N")),SUMPRODUCT(('Training Data'!$B$5:$B$568=F$28)*('Training Data'!$C$5:$C$568>=F$30)*('Training Data'!$C$5:$C$568<=F$32)*('Training Data'!$D$4:$CF$4=$F$34)*('Training Data'!$D$3:$CF$3=F$36)*('Training Data'!$D$5:$CF$568>0)*('Training Data'!$D$5:$CF$568<>"N")))

    Thank you for your reply, Mr. Topley. That formula does in fact work for the given set of data, except it also counts the "P" (Planned) as attended. However, I've gotten around that problem by creating a helper cell and subtracting the "Planned" from the "Attended".

    Thank you everyone for your replies! It's very much appreciated. I will go ahead and mark this thread as solved at this point. Even the suggestions given that weren't directly related to my issue here will definitely come in handy as I get more familiar with the advanced formulas in excel.
