2. Pick anywhere NOT on the scene objects to clear the Pick.
3. Now you'll be needing that extra bonus trick I mentioned.
Add Inquire("is not empty") (or "is not null")--I can never remember which it is until I hook it up and run it.
Feed the Pick to Inquire. Also feed the same Pick to the second input of Route.
Feed the output of Inquire to the 1st input of the same Route.
Then take the output of Route to Extract, disconnecting the output of Pick that you have now.
In other words, Inquire determines if there is a Pick or not, then Route either shuts it off if no pick (Inquire returns 0), or passes it if there is a Pick (Inquire = 1). No pesky error messages when the Pick is empty (or null, whatever).

Thank you so much for your comprehensive reply!
I think I got most of it figured out now, but I has just another question.
I have this connection
Pick_1 à extract ("data") à select à format à caption à collect (which also has the objects collecting here) à image, image, image (three branches to image views)
When I run it, I get this error "FORMAT: Bad parameter: template must be a string"
I didn't make any changes to any of the tools, expect pick_1, in which I checked the interpolate box, and set it to 1.
Any ideas?
Thanks soo much,
Dave
p.s. do you know hwo to get rid of the previous picks? Once I want to select a different pick, the last one doesn't go away.
