# How to create formulas on the fly in Excel 2010

I want to have the values "32" and "41" within the formula "=COUNTIF(Numbers!\$E\$32:\$E\$41,A4)" calculated from the value of some cells, say A1 and A2.

So I'm assuming you want the row numbers to be in cells A1 and A2?  So if you have a list of 100 items, you want to enter A1=25 and A2=50 then count between rows 25-50 for the value you are seeking?  Is that correct?  If so:
``````=COUNTIF(INDIRECT("E"&A1):INDIRECT("E"&A2),A4)
``````
would be what you are looking for.  INDIRECT takes a text value reference address and returns the value of that reference.  In this case we are constructing the string "A" & "value of cell A1".  Therefore, if A1=25, indirect returns A25 and that becomes the first address of the CountIF statement.

If you need the columns to be entered separately too, you can probably figure that out based on this example or you can post back and I'll give you that code also.

HTH.

I found the solution:

First
=COUNTIF(Numbers!\$E\$32:\$E\$41,A4)
was changed to:
=COUNTIF(INDIRECT("Numbers!\$E"&((\$A\$1-1)*(\$A\$2)+2)&":\$E"&((\$A\$1)*(\$A\$2)+1)),A4)
and
=SUMIF(Numbers!\$E\$32:\$E\$41,A4)
was changed to
=SUMIF(INDIRECT("Numbers!\$E"&((\$A\$1-1)*(\$A\$2)+2)&":\$E"&((\$A\$1)*(\$A\$2)+1)),A4)

Thanks, everyone that tried!

Please, give Andrew Hancock the points, he earned them!  I just did not complete the form correctly, my bad.  I gave him an 'A' thinking that would trigger him getting the 500 points.
