i'm running into little issue,

I created an Incident Field labelled "Deferred Reason" which contains 10 different options. Technicians would select one option and a Business rule would then be applied and change the status to hold.

My problem is:

1. If a technician updates the ticket with anything, a alert gets sent out everytime, as any change causes the Business Rule to go off

2. If a techician goes into the ticket after and changes the status back to open, when they hit save the business rule kicks in and changes the status back to On Hold ( unless they go down to deferred and select a option that not in the rule)

Would there be anyway to have the business rule only kick in if something was actually selected again in the new option i created under "Deferred Reason". So i nothing in that field actually changes, do not initiate business rule?
