I have a table with 6 columns and a variable number of rows. Column 2 and column 4 are checkboxes. I need to test whether any of the checkboxes are “checked” and set a flag if at least one is checked. Is there a simple way of doing this? I have tried by adding an invisible numeric column and setting it to “1” if either column is checked. This works on a row by row basis, however I can’t find a way of totalling all rows.
