"thank you"-site in php-email-form don't appears

hello kirupa-team,

why my email-form (from http://www.kirupa.com/developer/actionscript/flash_php_email.htm) works perfect when i try the kirupa-original-file, but don’t work anymore after i but the form in a flash (fla) movie-clip which is a menu-point of my existing website.

strictly speaking the email-message arrives to my defined email-account, but the second site of the form (which says “thank you for you input !”) don’t appears, after i have clicked the “send”-button !

i have tried to find the error for many many houres, but i couldn’t find out what’s wrong.

it would be very kind, if everyone can give me a hint.

thanx a lot
to everybody
