another question about CreateUserWizard

[Dan]

Hi,

i created a CreateUserWizard and i changed a little bit the error text (e.g.
if no email is entered: "an email is required".
When i create an user an di forgot to fill a email, i don't see the error
text, only a red star behind the textbox.
How can i show that error text? If not possible, why "ErrorMessage" in the
tag?

Thanks
Dan
