Delete Visitor Message

[Infinity101]

Hello, I've been working on a link to delete a visitor message on a profile rather than doing it the default way. Currently, I have been using a iframe to a template which uses the form code, however for obvious reasons I would rather use a href.

I've tried several variations, however the output page is bank with a 0.

Example of what I've tried.

PHP Code:

a href="visitormessage.php?{vb:raw session.sessionurl}u={vb:raw userinfo.userid}&do=deletemessage?rb_del_hard&vmid={vb:raw message.vmid}" 


Any ideas on how to get this to work? Thanks.
