ISR Adobe Form Validation

hi,

In ISR Adobe Forms I have 2 textfields where the user can enter the telephone no and email id .I want to do validation.So I have given the validation pattern as '('999')' 999-9999 and A'@'A'.'AAA.But it is showing "Field Validate Failed"..

What is the reason?

Can anyone tell me the steps how to validate the fields in adobe form..

Regards,

Rheema Rahael.
