I have a field checkbox contain multiple values, eg, A,B,C,D,E
I want to force C to be selected if D is selected, but not forcing D to be selected if C is selected.
So if D only is selected, C+D must/will be selected
But if C only is selected, he can select D but does not have too.
real examples is for program selection in a conference registration,
eg.
conference (paid event)
short course (free event for conference participant, otherwise has to pay)
field trip (paid event)
so, one cannot select short course only in the hope to get free stuff only. but one can freely choose (or choose not) to attend short course if he/she register for conference
how do i go about it using field validation?
thanks
hendro
