Thanks for posting insertvalue.fp7 that really helped getting a handle on inserting data - I was using a replace function with the GetFeildByName script step . I've attached a file of what I've done. I bundled $$Start, $$end, and active field data into one variable array and used Goto Object to limit this to one script for multiple fields. Also used a button to capture field and cursor position to limit the need to attach a scrip trigger to all fields on the layout and stuck with a value list on the field. Still needs some tightening up but wanted to get something posted. Thanks.
On a final note Is it possible to get a fields pop up to activate via script?
