COUNTIF/SUMPRODUCT??

[Peta]

Hey if anyone can help it would be much appreciated!

I have a column of 6 cells which can have either A/B, C, D, E etc typed in
them in any order. I need each letter/s to link directly to a particular cell
if typed in any of the 6 cells. If for example D1=C and D4=D then the links
to those two letters need to sum.

The formula I have that doesnt work (and is probably completely wrong) is:

=SUMPRODUCT(--('Exec Sum'!$D$8:$D$13="A/B",'Uplifted NIA to GIA
ft2'!C57,IF('Exec Sum'!$D$8:$D$13="C",'Uplifted NIA to GIA ft2'!D57,IF('Exec
Sum'!$D$8:$D$13="D",'Uplifted NIA to GIA ft2'!E57,IF('Exec
Sum'!$D$8:$D$13="E",'Uplifted NIA to GIA ft2'!F57,IF('Exec
Sum'!$D$8:$D$13="F",'Uplifted NIA to GIA ft2'!G57,IF('Exec
Sum'!$D$8:$D$13="G",'Uplifted NIA to GIA ft2'!H57,IF('Exec
Sum'!$D$8:$D$13="H",'Uplifted NIA to GIA ft2'!I57,0)))))))

Not sure what you want to do.

Need more information.

It is for a cost management spreadsheet to track total costs of a
construction project over time. Time taken on the project is split in to four
stages and each completion stage is classed by A/B, C, D, E etc. These
letters need to be entered in to either of the four stages (time)-(a matrix
type setup), and as soon as a letter is factored in, it needs to
automatically link the cost information from for example 'C' stage of
project, from another sheet (projected costs) and add them in to the running
total work sheet.
It also needs to ignore the blank cells that are yet to have letters entered.

Does this help? Thanks for looking
