I don't know what it could be...

I just tested this exact code on my test forum:

PHP Code:

global $vbulletin;

if ($vbulletin->userinfo['field7'] == "GIRL")
{
     $user['musername'] = '<span style="color:pink;">' . $user['username'] . '</span>';
}

else
{
     $user['musername'] = '<span style="color:blue;">' . $user['username'] . '</span>';
} 


And made field7 BOY / GIRL just like your settings and it works just fine.

The problem for you is that:

PHP Code:

$vbulletin->userinfo['field12'] == "GIRL" 


is NEVER being evaluated as "true" even when it should be...

Just for a test measure why not add this line to the top of the code:

PHP Code:

echo "|" . $vbulletin->userinfo['field12'] . "|"; 


It should write out at the very top of your forum something like |BOY||BOY||GIRL||BOY....

I'm curious if says anything at all... if it does copy and paste it here...

Be sure to remove the line after you run this test so it doesn't mess up your forum for everyone.
