Allow MyCode In Profile Fields

[Newman]

Ok I have a problem when I'm calling only 1 PRofile function..

example: http://community.mybboard.net/showthread.php?tid=29444

I'm calling out this (I enabled it to have mybbcode)

{$userfields['fid4']}

Because I only wanted that 1 code to show, but it doesnt show the mybbcode.
Can you tell me how to make it allow? thx
