hi all!

let say i have 2 fields. 1 is creation date(it will automatically fill the current date). and another 1 is due date (drop down calendar)

what i wanna do is, if someone choose a date from the calendar which is before the current date, custom dialog will appear...

but i donno how to do it..

someone help me plz

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 !)

tq. i'll try it
