Working out the number of people on treatment on a day (and then for every day)

How about providing us with a sample workbook so we don't have to make-up data?

Attach a sample workbook. Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

Click on GO ADVANCED and then scroll down to Manage Attachments to open the upload window.

Maybe try as attachment.

ALL ARRAY FORMULA:

...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer.

Hi,

The paperclip 'Attach' icon doesn;t work - no don't ask!

To attach a file choose the Go Advanced button and look underneath the post area for the 'Manage Attachments' option and take it from there.

Is it really the case that you only want to see the number being treated for just days from 20/10/1981 to 14/11/1981 and for months from Oct 81 to Nov 83?

Or in fact are you looking for information for any of your days and months through to the last date in your data of 5/10/2017?

Does the absence of a date in the date removed column mean that you count a 'patient treatment' incidence on every day from the start date to the current date, or are you only interested in records which have both a start and removed date?

Does the attached help.

I first had to convert all your dates to proper Excel date numbers since they were all text values and although you can use the DATEVALUE function to convert within a larger formula I prefer to deal with original date numbers. To convert them all just enter a zero in a cell, copy it then choose the whole of columns B & C and use Paste Special Add - which adds zero to all the 'dates' and forces them to become date numbers.

For a particular day enter the date in G2, the table of months in G4:H4 down counts the number of start dates within the month which don;t have a removed date.
