Hi! I need to make a simple tabl

[saramaia]

Hi!

I need to make a simple table and rows are several dates. I have a group for this in the field DATE. For each date i show different values, namely, number of times that date ocurs in the table. I inserted this value as a grand summary.


In the end of the table i need to divide a certain value given by a formula for the number of times the date of the row ocurs.

The problem is when i build the formula to make the division i don´t have the value containing the number of times the date ocurs because that is a grand summary and it´s not available to be used in formulas.

How can i get over this problem??

Thanks
