Ok, gonna try to explain this as best as I can.

I need a formula on the Summary tab (see the yellow) that will essentially insert the respective Code with the Project Number. I have been able to manage to to that, but when I get to the "Totals" and "Group B projects" on the Pojects tab, it ithrows off my formula by two.

Is there a formula to ignore the two blank values on the Summary Tab in cells B 24 and 25? Because wehn i copy them down the column, it throws off my Index Match formula. See the red on the Summary tab.

=INDEX(Projects!$B$4:$B$45,MATCH(Projects!C4,Projects!$C$4:$C$45,0),0).

wrt1mea,

You could use:

=VLOOKUP(A4,projects,2,0)

It's in the attached file.

Or

=INDEX(Projects!$A$4:$C$275,MATCH(A4,Projects!$A$4:$A$275,0),2)


If you prefer.

patrickab,

I was attempting to use an index match...what does the 2,1 at the end help do?

>.what does the 2,1 at the end help do?

Column 2, area 1 - only one area was specified as only one range was declared.

BTW ther is no advantage in using Index as opposed to VLOOKUP() in this instance.

Well, I should have done a better job with the example and explanation. the main information I will be referencing will not be in the first column...

Patrick's VLOOKUP suggestion would seem to be fine, you can always adjust the formula so that the lookup range is a different column.

INDEX/MATCH is also possible, sometimes preferable, when the data to be returned is in a column to the left of the lookup range then INDEX/MATCh is the standard approach but that doesn't seem to be the case here, can you explain what you need to do that you can't do with VLOOKUP?

OK,I always thought that the limitation to vlookup was the the particular cell you are referecing had to be in the first column. If I was wrong about that, my apologies for not completely understanding. The index match formula he provided worked great.

With VLOOKUP the lookup value is always looked up in the first column of the range you specify, so with

=VLOOKUP(A4,B:C,2,0)

A4 is looked up in the first column of B:C, that's column B, of course if you want to lookup a value in C and return the corresponding row from D then you can just change the range, i.e.

=VLOOKUP(A4,C:D,2,0)
