Hi Tom,

Thanks a lot. You were right about CompareValidator. For some reason I thought that this control was used only to compare between to values but it also does datatype validation. So to verify that the user enter a good date I placed Compare and requiered validators.

If I want to use javascript for another tasks do you recommend to place javascript on the asp file or "injected" on the codebehind?

Thanks again,

William
