Hi,

One possibility:

=IF(A1="",0,IF(AND(B1<"",C1<""),"Delete a date (Col B or Col
C)",IF(AND(B1="",C1=""),0,IF(B1="",C1-A1,B1-A1))))

Hope this helps,

Regards,

I use the following formula to calculate the days between 2 dates €“

=if(or(A1="",B1=""),0,B1-A1

How would the formula look if I wanted to add another column say €˜C1 €“
and then for the result to be calculated according to which cell had a
date entry e.g. either B1 or C1 - that would then minus A1?
