Toggling Data on/off

[pointb]

How have a field that is a sum a various fields.

One of them is a percentage fee that needs to be applied 50% of the time.

the percentage is calculated automatically, and I'd like to know how to be able to toggle that field on or off.

is this possible?

thanks

I'm not exactly sure what sort of behavior you would like to see. You could create an "Toggle" as a number field that contains 0 or 1 and then display it as a checkbox or radio button. You would then use this in the percentage calculation field with an 'If' statement to give different results depending on whether the toggle field = 1 or 0.
