@kotab 

can you share the complete script?

are you sure you are giving the correct variable names?

any other UI policy is conflicting?

If my response helped please mark it correct and close the thread so that it benefits future readers.

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

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

        return;

    }

    var variableNames = [

        'cost_code'.............

    ];

    var makeMandatory = (newValue == 'Azure');

    // Loop through each variable and set it as mandatory or not

    variableNames.forEach(function(varName) {

        g_form.setMandatory(varName, makeMandatory);

    });

}
FYI : i took correct variable
No UI policy
