I would like to do pretty much the direct opposite to the not() function.
I want to disable a checkbox if another checkbox is checked. The other way round (ACTIVATING when checked) is easy and you find a lot of tutorials telling you how to use the not() function for that.
I have the following situation:
There are two checkboxes. As soon as one get checked, the other should be disabled (and the other way round).
How can I achive this? This should be possible with a simple rule, shouldn't it?
Thanks in advance,
Solved! Go to Solution.
opposite of not() function is double not(not()), or do not use it at all
for your scenario rule are definitely the most suitable.
checkbox (Yes/No control) evaluates directly to true/false, so your rule's formula will be very simple - just a reference to the counterpart checkbox
