Confirm Dialog box in Servicenow

[KS86]

Hi all,

I have one requirement.

I have one field called group on the catalog form. 

We have one MRVS, it contains filed group. Group field will be populated with value based on the Group field on the catalog form. 

Requirement -

Select group on the form, add values in MRVS. Then if we try to change the group field , it has to show one Confirm Message("If you change the group, it will clear the all rows in MRVS").

1. If user click "Ok", MRVS rows has to be cleared and Group has to show with new Group Value. (Working as expected now)

2. If user clicks on "Cancel", Group has to show the Old Group only. 
Currently #2 is not working as expected.

g_form.setValue('u_group', oldValue); // This is not working. 

Please let me know if you guys have any thoughts on this. Thanks!

I can't share that due to confidentiality.

    if (g_form.getValue('assignment_group')) {//if assignment_group MRVS has values

        if (confirm("Changing group will clear your rows in MRVS. Continue?")) {

            g_form.clearValue('assignment_group');

        } else {

            alert(oldValue);

            g_form.setValue('u_group', oldValue);

        }

Here is the script , that's all I can share

    }

@KS86 

so "assignment_group" is variable within MRVS?

what's u_group?

without these details it's difficult to understand
