Comparing Actual end date and Planned end date

[Vinutha BJ]

I'm trying to compare to dates in change request form but it's not going inside if loop

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

var actualEnd = g_form.getValue('work_end');
 var plannedEnd = g_form.getValue('end_date');

if ((actualEnd >= plannedEnd)) {
g_form.addErrorMessage('Actual end should be lesser than or equal to Planned end date ');
 g_form.clearMessages('actualEnd');
}
