What is your current formula in the cell?
have you changed the name of a worksheet?
In order to add together in Sheet1, say,
Sheet2!C4
Sheet3!C4
Sheet4!C4
use
=SUM(Sheet2:Sheet4!C4)

The worksheets name changes from month to month!
These are Week Ending dates. I need to calculate total production for a month. I have been trying to simplify this spreadsheet and hit this snag. When I have a group that has had no production over the last few weeks all those blanks add up to #VALUE! . I want to get rid of this and leave the cell empty when there is no total.
Chuck,
Adding blank (that is, empty) cells should result in zero, not in #VALUE!.
My guess is that you might have text in (one of) those cells, e.g., a space (that is, " ") or a formula that returns a blank ("").
Try the following formula to see whether this is true:
=IF(LEN('WE 10-7-01'!I8)>0,'WE 10-7-01'!I8,0)+IF(LEN('WE 10-14-01'!I8)>0,'WE 10-14-01'!I8,0)+IF(LEN('WE 10-21-01'!I8)>0,WE 10-21-01'!I8 ,0)+IF(LEN('WE 10-28-01'!I8)>0,'WE 10-28-01'!I8,0)+IF(LEN(BLANK!I8)>0,BLANK!I8,0)
If this comes out right, I'd suggest to change the formula in I8 everywhere to return 0 instead of "" or " ".
