Try the ISBLANK() function, for example:

=IF(ISBLANK(A1),function_if_blank,function_if_non_ blank)

Does that help?

I'd like to set up a formula (function?) that says,
If this cell is blank, then use this formula.
If the same cell has data, then use this forumula.
But I just can't figure out how to do it. Any help would be great.
I know the two formula's I want to use, I just don't know how to direct the
cell to the right one.
