Distinguishing between a NEW record and an Existing record using Custom Content

Hi All,

In Sage CRM 7.1 SP2 i have code placed in Custom Content that Disables fields and will Enable them when a onchange has been made to another field. To add to this i want to be able to apply this code to ONLY when a NEW record is created and not existing records.

Please advise the best way to accomplish this using Custom Content?

Kind regards
