ohh I see what I did wrong last night I did what you said as well and there was a php syntax error in my code and i didn't pick up on it.
but now I fixed up the line and I used
header('Content-type: text/vnd.wap.wml');
thanks any way.
are you willing to share your validate_email.php script on your site?
