Replace comma with dot in currency field

[Jo_o Pedro]

I'm trying to replace a comma for a dot in a currency field but I'm failing with the script

This is the script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var contractCost = g_form.getValue('u_contract_cost');

    var dot = contractCost.replace(/,/g, '.');
    g_form.setValue('u_contract_cost', dot);
}

This is the field and the error that is returning

IT is probably down to your browser or users Locations. This is the probable solution.
