Get information from one variable set to another

[asd22]

Hello.

Im making a catalog item, that is gonna be used to look up users in a reference field. Then when you select a user his/hers information will auto populate the fields in the catalog item.

Variable set A, that's where the user basic information gets collected, Here i select the name and the users ID, status gets auto inserted into fields.

Then i have Variable set B. Here i have "account expire date", where i want the users account expire date to be auto filled in. The only issue, i need to get variable set B to notice when variable set A gets changed, how do i do this?

This are my current catalog client scripts:
Variable set A 

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

      return;

   }

    var userref = g_form.getReference('varA_name', userLookup);

    function userLookup(userref) {

        g_form.setValue('varA_employeid', userref.user_name);

    }  

}

Variable set B

function onChange(control, oldValue, newValue, isLoading) {

   if (isLoading || newValue == '') {

      return;

   }

    var userref = g_form.getValue('varA_name', userLookup);

    function userLookup(userref) {

        g_form.setValue('varB_accountexp, userref.account_expires);

    }  

}

Hi @asd22 

You will need your client script to be on the catalog item which has the variable sets linked to it.

so i should move both client scripts out of their variable set, and have them as client script on the catalog item?
