Nested Formulas conflict

[roma83]

Dear all,


Hope I can explain this clearly:

If Cell E has a figure and Cell F is empty Cell H should return a number BUT if Cell E + Cell F are larger then 200 cell H shall return "do not supply"

I have the below formula, however they seem to be conflicting with one another.

=IFERROR(IF(E222=200,"250",IF(E222=250,"200",IF(SUM(F222+E222)=0,"250",IF(SUM(E222+F222)<200,IF(E222>=250,MAX(0*SUM(250-E222),0),"200"),"do not supply")))),0)

Thank you and regards

1. This part doesnt make sense

MAX(0*SUM(250-E222),0)

Anything mulitiplied by zero is zero. Therefore you'll get the maximum of zero... or zero ????????

2. This also doesnt make sense

SUM(250-E222)

This is simply 250-E222, you're not SUMming anything.

3. =IFERROR(IF(E222=200,"250",IF(E222=250,"200",

I suspect this should be

=IFERROR(IF(E222=200,250,IF(E222=250,200,

without the quotes.
If you use quotes you are returning a string.

Your logic seems incomplete. What happens with E =100, F =100... and is it the SUM of E&F >200 that returns "DNS" or BOTH E&F > 200 returns DNS.

This is just a correction of your original formula, not a solution.

=IFERROR(IF(E222=200,"250",IF(E222=250,"200",IF(F222+E222=0,250,IF(E222+F222<200,IF(E222>=250,MAX(250-E222,0),200),"do not supply")))),0)

this may need refining because of your incomplete logic.

You seem to be saying

If E and F have both contain numbers and are > 200 then return "do not supply"

but what does this (below) mean?

"If Cell E has a figure and Cell F is empty Cell H should return a number"

What number and what are the rules governing this?

I used this because i do not want negative values. When I applied it it worked.

See Qs at post 3... It's also a good idea to make it clear WHO you are replying to.

"If Cell E has a figure and Cell F is empty Cell H should return a number" The number is 250.

The number are just a direction from my head.

We are supplying our patients every two months.

For the first two months January and February we give them 250 units.

For the second two months March and April we will then give them 200 and so forth.

BUT if they are given over 250 units in January and February, no units will be given for March and April.

In fact I m still working on it. It should return "250"

I think we need to see a sample sheet.

Will you please attach a SMALL sample Excel workbook (10-20 rows of data is usually enough)? Please don't attach a picture of one (no-one will want to re-type all your stuff before starting).

1. Make sure that your sample data are truly REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired solution is also shown (mock up the results manually).

3. Make sure that all confidential information is removed first!!

4. Try to avoid using merged cells. They cause lots of problems!

Unfortunately the attachment icon doesn't work at the moment. So, to attach an Excel file you have to do the following: Just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.
