Current value not returning in Business Rule

[M_iA]

Please could someone take a look over my script that ive written and help me out?

(function executeRule(current, previous /*null when async*/ ) {
    var user = gs.getUserID();
	var contact = current.contact;
    gs.info('MIIA User ID: ' + user);
    gs.info('MIIA Current Contact: ' + contact);

    if (contact == user) {
        gs.info('MIIA User is the contact.');
        return;
    } else {
        var grUser = new GlideRecord('customer_contact');
        if (grUser.get(user)) {
            var userHelpCentreProfile = grUser.getValue('u_help_centre_profile');
            gs.info('MIIA User Help Centre Profile: ' + userHelpCentreProfile);

            if (userHelpCentreProfile == '3') {
                current.addQuery('sys_class_name', '!=', 'sn_customerservice_case');
                gs.info('MIIA Query added to hide the record.');
            }
        }
    }
})(current, previous);

I am trying to allow a user to view the tickets that they raise and are the contact, but then if not the contact, then to exclude a certain class.

The log returns no value when i log in as the user and create the ticket:

MIIA Current Contact:

I don't know that I'm exactly following that - I'm sure it will make sense tomorrow.  With what I caught it seems like you can follow what the BR is doing, but add different logic for 1 and 2?  Upon looking at my script again, I see it would be better to get the profile once, then go into the case GR, so something more like this:

(function executeRule(current, previous /*null when async*/ ) {
	var caseArr = [];
	var user = gs.getUserID();
	//gs.info('MIIA User ID: ' + user);

	var grUser = new GlideRecord('customer_contact');
	if (grUser.get(user)) {
		var userHelpCentreProfile = grUser.getValue('u_help_centre_profile');
		gs.info('MIIA User Help Centre Profile: ' + userHelpCentreProfile);
	}

	var caseGr = new GlideRecord('sn_customerservice_case');
	caseGr.query();
	while (caseGr.next()) {
		if (userHelpCentreProfile == '1') {
			//do something
		} else if (userHelpCentreProfile == '2') {
			//do something else
		}
		else if (userHelpCentreProfile == '3') {
			if (caseGr.contact == user) {
				gs.info('MIIA User is the contact.');
				caseArr.push(caseGr.sys_id.toString());
				gs.info('MIIA case added to list.' + caseGr.number);
			}
		}
	}	
    current.addQuery('sys_id', 'IN', caseArr.join(','));
})(current, previous);

 where you would also push the cases to the array if whatever criteria for 1 and 2 are met - or always if that works.  You might also need to incorporate standard/admin since this BR will run for everyone - if it turns out that admins are missing some cases.
