I have three columns of data that each have a sum at the bottom. (Tehy sum
vertically) I want to add a check box to the right of the last column and if
I select to check off the box. I dont want the data in that entire row to be
calculated as part of the three different sums for the all three columns. I
do have hundreds of rows that are displayed in those three columns. How do I
make this work ?
