Selim,

In Excel XP, the max length of formula is 1024 characters. If you are exceeding this length, you have to make it shorter...put subcalculations in other cells.

>I'm triying to fill an excel sheet trough automation, I store references to specifics cells that store subtotals to make a formula to a total, when the group is finish I try to store the formula in a cell and I got the message "Formula is too long" any workaround for this?.
