setValue variable MRVS in client Script Onchange ()

[Rick Larson]

Hello everyone, I have an MRVS and in it there is a selectbox variable, I would like to set the value according to a variable that is outside the variable set, Example

if ( g_form.getValue('variable_out_of_mrvs') == 1 ) {

g_form.setValue('variable_selectbox', '2') }

I know that MRVS is a JSON and that way it won't work, I would like to understand how I could do it.
