I would like to set-up some type of rule, that if my "Account Type" equals X, then I want a Related List to become mandatory that it is completed and updated. Can such a rule like this be completed in the Professional edition?
Don't know if you need to know the following;
"Account Type" is a custom field in the Account object.
The Related List is a new custom object, which is also situated in the Account object.
