Using custom profile field contents in condition

[Cadellin]

I want to create a custom permission for my members to allow them to hide their instant messaging information if they select a radiobutton.

So my question is if I have two radio buttons (Yes/No) called field9 how can I use that in a condition to hide or show content?

I understand about vB conditionals but I always know I can't use vb:raw in a conditional - so how can I do it?

Thanks in advance
