How to remove options from select box if user is not part of assignment group

[Piyush291]

Hi,

I have a requirement where i have to remove options from select box if user is not part of the group.

but i  have around 50 groups in which 1 is incident group and other 49 starts with IN - Incident, SO i need to add condition in script include, my below script is not working

var getgroup = Class.create();

getgroup.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getFulfillmentUsers : function(current){

var grUsers = [];

var grMember = new GlideRecord('sys_user_grmember');

        grMember.addEncodedQuery('group.name=Incident^ORgroup.nameSTARTSWITHIN - Incident^user=' + usrID);

        grMember.query();

        while (grMember.next()) {

            grUsers.push(grMember.user.sys_id.toString());

        }

        return grUsers.toString();

},

    type: 'getgroup'

});

Can someone help me with the Script include and client script
