What is wrong with this code?

[Christine]

I am trying to set up subscriptions, and need to block style selections for free members. I can't do an is IN (x,y) in the modifyoptions and footer templates as it gives me an error saying that IN isn't one of the options I can use for conditional functions.

I tried this in phpinclude_start, but it isn't working either:

PHP Code:

if ($bbuserinfo['membergroupids'] IN (20,21))
}
$vboptions['allowchangestyles'] = 1;
} else { 
$vboptions['allowchangestyles'] = 0; 
} 


I know I am missing something simple here, but I don't know what.

Can anyone help?
