problems using PUT

Hello,

I hope someone can help as i've been stuck on this for a while now. The
below code errors with the following : Not a SCALAR reference at
/usr/lib/perl5/site_perl/5.8.
8/HTTP/Message.pm line 156.

I know that this is because @form_data is an array, not a scalar, but I
can't seem to get the right syntax to convert it to a scalar.

Any help would be greatfully recieved.

Regards,

Paul
