Hi

to show a custom dialog you'll need a plugin.

But to show a custom message, the lonely thing that you have to do is to insert this calc into the validation option of the field "dueDate":

dueDate ≥ creationDate

and flag the "display custom message" box.

(naturally you'll have to enter your custom message !)
