Add that javascript to a new template, I'll call it template1, in your phpinclude template add:

PHP Code:

if ($bbuserinfo[usergroupid]==X) {
    eval ("\$disableselect = \"".gettemplate("template1")."\";");
} else {
    $disableselect = '';
} 


Change X to the usergroupid and template1 to the template name, and add $disableselect to your headinclude template.
