non-admin try to Add group

[Rafael Batistot]

Hi Team

To add a a group in a specific user i'm using this script. Is not a beauty code, but work 

var users = current.variables.select_the_user.toString().split(",");
var arrayGrupo = current.variables.group_associate.toString().split(",");

users.forEach(function(userSysId) {
    arrayGrupo.forEach(function(grupoSysId) {
        var groupName = utils.getGroupName(grupoSysId);
        addUserGroupWithId(userSysId, grupoSysId);
    });
});

function addUserGroupWithId(userID, groupID) {
        var userGroupGR = new GlideRecord('sys_user_grmember');
        userGroupGR.initialize();
        userGroupGR.user = userID;
        userGroupGR.group = groupID;
        userGroupGR.insert();
    },

i've applicated in a business rule to trigger when a non-admin try to add an user a specific group 

besides not work i'm facing this issue in the log. 

Add user in group(56c2540c470cf610cbcc97a4116d4384): ReferenceError: "item" is not defined. (#0(eval); line 97)

With Admin works normally, i checked:

ACL,
Business Rule,
Script Include,
UI and DATA polices
Client Script... everything, bot not found 

if anybody got the same problem i would like to hear you. 

Thank's advance
