When entering a new Client on our file - after entering the family name field I have put the following script to jump to the Postcode field (if there is no address line 1 there) into the OnObjectExit trigger. When I run in debug mode I can see it correctly goes to the Postcode field but immediately jumps back to the following field in the tab order afterwards.
If [ IsEmpty ( CLIENT::d_Address_1 ) ]
Go to Field [ CLIENT::d_Address_6_Postcode ]
[ Select/perform ]
Your help appreciated!
