IsEmpty ( FilterValues ( CheckBoxField ; "specific value Here" ) )
Will be true if the check box for "specific value here" is not selected.
Thanks for this! I've now tried to use this function, but cannot get it to work properly. My script looks like this:
If [IsEmpty ( FilterValues ( "MyTasks" ; "Task 1" ) )]
Set Field [TestDatabase::Checkbox Check; "Yes"]
Set Field [TestDatabase::Checkbox Check; "No"]
The value list is "MyTasks". The checkbox is called "Task 1". Unexpected thing (for me) is that my field "Checkbox Check" is always filled with "Yes". If I change the state of the checkbox and then run the script, I always get "Yes", which is not what I would expect. What's going on here?
The 'CheckBoxField' in Phil's answer was to be replaced by the field, not the literal text "MyTasks".
Thanks, that did the trick!
