I have the following situation.  

I have 2 checkboxes.   One checkbox (CB1) that has a ui policy to show additional variables and other checkxbox (CB2) doesn't.   What I don't know how to do is to have a checkbox unchecked if another checkbox is checked.  

I have a ui policy that hides CB1 if CB2 is checked.   That works fine but the problem is that if CB1 is selected and because it has a ui policy that shows additional variables, the additional variables are still visible even though CB1 is hidden.  

I think I think I need to write a catalog client script for this but I am not script savvy.   Please help

Here is what I which is doesn't work:

Type: onChange

Variable name: cb_2

Script:

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

    if (isLoading || newValue == '') {

          return;

    }

    //Type appropriate comment here, and begin script below

if (newValue == true){

g_form.setValue('cb_1' == 'false');

}

}
