# Excel/MATCHing a date within a range of dates

Question
QUESTION: Tom, I hope I can explain this clearly.

I have a list of names in column B, amounts in column C, and dates in column D. Entries can be repeated in any column.

Then in column A, I concatenate each row.

I would like to MATCH name&amt&date in column A. HOWEVER.....the date can vary from 5 days before to 5 days after.

So my question is: how can I MATCH("DOG"&23.54&42385,\$A\$2:\$A\$100,0) so that it returns the location in A of an entry with DOG, 23.54, and the first date within 42380-42391?

SUMPRODUCT? Array formula? Something else?

I'm using Excel 2003, and want a formulaic solution. Not VBA.

so match returns the row of the match.  I am guessing you want the row.

=SMALL(IF((\$B\$1:\$B\$500="DOG")*(\$C\$1:\$C\$500>=23.54)*(\$D\$1:\$D\$500>=42380)*(\$D\$1:\$D\$500<=42391),ROW(\$B\$1:\$B\$500)),1)   entered with Ctrl+Shift+Enter rather than just enter since this is an array formula

should give you the first row where the conditions are met.   Also, it doesn't use the concatenated values in column A but goes against the original data.

Hope that works for you.

Note the hard coded values like "DOG" in the formula can be replaced with a cell address that points to a cell that holds the word "DOG" or whatever criteria you want to work with.

QUESTION: Oh, this is returning the row number instead of a MATCH value. Excellent! Just what I was looking for.

I don't want to hardcode a date in there, but simply use a reference instead. In that portion of your formula, may I:

(\$D\$1:\$D\$500>=\$D2-5)*(\$D\$1:\$D\$500<=\$D2+5)

If that will work, then it fills my needs perfectly.

Thanks, Tom!

Yes,  (\$D\$1:\$D\$500>=\$D2-5)*(\$D\$1:\$D\$500<=\$D2+5)  should work.   If you have any problems then do

(\$D\$1:\$D\$500>=(\$D2-5))*(\$D\$1:\$D\$500<=(\$D2+5))

but by order of precedence, the plus and minus sign should be evaluated before the comparison operators.

QUESTION: At first this formula resulted in a column of errors, Tom, but as I've been tweaking and playing with it for the past couple of hours, I now have many more values. But darn it, certain entries still result in VALUE or NUM errors no matter what I do.

I added in the criterion (IF(\$E\$8:\$E\$744="A","B","A"))

I believe I learned at one point that certain functions or constructs don't work in array formulas. Will a nested IF like that work? (It's inside the main IF you gave me.)

Is there a list somewhere of the items that don't work in arrays? Gosh, I'd love to see it if so!

Thanks so much for your time.

I would have to see how you are using it, but all the other conditions produced a true or false condition which is converted in the formula to a 1 or zero.   The statement you show is returning an A or B string value so it seems inconsistent with how the formula was originally built.

If you want to send a small sample workbook and tell me what you want to do, I can see if I can show the way.

I believe that was I was trying to do was simply too complex and I've decided to simply. But, I loved learning the trick using SMALL and ROW with an array. What a great asset that will be to me! I hope to find many other uses for it in the future. Thank you again for your time.
