PHP Mailer / Permissions?

I have a PHP Mailer that i’ve incorporated into my Flash file. I’ve used it in the past and it has worked and i’ve received the email with the relevant details.

I’ve gone to use it again and i’ve also tried using the original template and alternated with a couple of different admin email addresses and it doesn’t seem to be getting through.

I was wondering if it had anything to do with the CHMOD/Permissions of the Flash file and PHP file.

Does anyone know of what a PHP file permission should be in this instance?
