If you mean that B6 = "AC" and you want to search for that within column C
on Sheet two, and then return the corresponding value in column A, then:
=IF(ISERROR($B$4),"AC not
found",INDIRECT("Sheet2!A"&MATCH("AC",Sheet2!$C$1:$C$100,0)))
Keep in mind that there could be other ways to accomplish the same thing.
Also, it is best to specify a range rather than using the entire column. In
my suggestion, I've used rows 1 through 100. You can adjust that as
necessary. Based on your example, it seems that you are saying that "AC"
will only appear one time. If that is true, then the formula above should
work without issue. If there is more than one "AC" and you want something
other than the first occurance to be found, then the above formula will not
work.
If this is not what you want, please give details.
HTH,
