Hi there asimshahiddIT,

Welcome to WebmasterWorld!

Could you post the relevant code so that we have a better chance of being able to help you with this issue. And obviously ensure that you have done the relevant debugging to make sure that the expected values are being passed to the mail function before your invoking it.

Cheers,
