[support] Passing multiple values into a single Views argument

I have a view where I have selected User:uid as an argument and I am using a sql query in the "Provide Default Argument" part. The problem is, usually, the sql query is passing muliple UIDs back. How would I pass all of them into the argument to be used by the view. At the moment, the view is only taking the first one. so, here is a simplified version of my php code: global $user; $result = db_query("SELECT node.uid FROM {node} WHERE node.type = 'profile'"); $member = db_fetch_object($result); return "$member->uid"; on my current db, this returns 3 UIDs...the view only takes the first one. Thanks Neil
