Button to go to new blank record if no related record exists
I have a button that will send me to the related record when I need to :
Parent Record : Collection Info Child Record : Trap Info
When I have a record saved in Collection Info and a related record saved into Trap Info, the button works perfectly. I related the two tables together by using ID Keys. Now, how would one use the same button, but when pressing it, if there is not already a related record saved in Trap Info, it will bring up a blank new record in Trap Info. Also, will the auto enter for ID and Foreign ID keys fill in their appropriate fields to now make them related records ?
