Validates email address only once, Why???

I am having problem with this code and was hoping if someone code guide me to the right direction.
I have the following form which validates username as a valid email address. However, if the email address is not valid once, it will show in the bottom of the form that email address is not valid. But if I hit submit button and it will submit the form and wouldn't look for validation.
Please fine the code below.
Thanks in advance

oops.
never mind, I was missing the validation group.
After that it works just fine.

I have a question though, since I am moving to ASP.NET from other development languages, could someone guide me to already built applications tutorials or eample codes besides the site asp.net

Thanks
