Hi, I've looked everywhere in this forum and can't find the exact answer I'm after.
I have a numeric field that starts with a fixed value of '44', and 6 checkboxes. For each checkbox selected I want '2' subtracted from '44' e.g. if 1 checkbox is selected the value becomes '42' and if two checkboxes are selected the value becomes '40' and so on.
Is this possible? I'm going crazy trying to make this work.
Thanks for any help.
