I would like to disable a checkbox based on conditions set in my script. I've got the conditional logic down, but I don't know what the control ID is for the check boxes using the standard check boxes dialog and they are not listed in the Common Definitions.sbi. As such, I am curious as to the control IDs for the check boxes.

If feature x is not selected then
Set Variable %optionsel% to 10
disable control ID Y

any idea how to figure that out?
