Hi Dominique, for each choice in your checkbox, on the ‘checkbox changes field data’ behavior, create a simple script using the simple branch to check to see if that particular option has been checked. If so, then use a set field object to uncheck the other option. Do this for both checkbox choices. This will automatically uncheck the other option.
hmm, thats very hard. I remember a simple functionality in Quask saying only one item can be selected from the ckeckbox…. I already found out this functionality is available in radio button check box, so it solved my problem for now….
