How to create a workflow on option set change before saving the record.
I have a scenario, like an option set value is changed dynamically through java script. Now we have to(run a work flow) for eg., add First Name and Last Name to Description.
I tried creating an work flow on the option set Record field change with condition check(If), but it is triggering only when the record is saved.
I want this workflow to trigger before saving the record or before hitting the save button.
