Custom Field Conditional Statements - Help

[Markro]

I'm trying to figure out how to implement a custom field in the users options area where if they select "YES" it will display a special box at the top of the forum, but if they select "NO" it will not display that box at the top.

Is this possible?

What is the conditional statement I should be using to achieve this functionality?

Thanks in advance.

Setup a user profile field, you can access the value to this field in templates using:
$bbuserinfo[fieldX]
