I have the following validation rule that works perfectly which makes mandatory [Customer] and [Member] columns if column [Feedback Type] equals "Ticket" from a drop down list:
=IF([Feedback Type]="Ticket",AND([Customer]<>"",AND([Member]<>"")),TRUE)
I need further validation rule but have no idea if it is possible to build further validations; what I also need is:
If [Feedback Type] equals "Ticket" or "Customer" from a drop down list then [Customer] and [Member] must be mandatory.
Ideally I would like also the following validation rule included:
If the column [Feedback Type] equals "Colleague" from a drop down list then [Colleague] must be mandatory but not [Customer] and [Member]
Hope the above makes sense!
Thanks
