I'm a complete PHP beginner experimenting with sending email via IMAP but hitting problems with variables.

I need someone to look through a single page of PHP code and correct where I've gone wrong in passing email via a PHP variable to the to and bcc fields.

Will be a simple job to do but need a quick turnaround within a day or so

Thanks!
