Form Hack question: parsing BBCode in variables

[IdealExchange]

Well, there's a 51-page thread on the Form Hack mod, if that's what you mean. Beyond that, I've read through various PHP tutorials (including the one linked in the sticky about coding). That's how I've managed to make the modifications that I have. This is the only one remaining that's giving me trouble.

I've been poking at this problem for a while, and figured it wouldn't be any skin off the forum's back to help me out with what I thought was a relatively simple question; I was led to believe it was the official forum for support. My apologies.
