sirLobito That works, but I think using a group would be neater :)
Make a variable - Countdown - with default value 3.
Create a text - txt_Countdown - make it say 3 for convenience
Put all your controls into a Group,
At the start of the layout, disable the entire group
"Every x seconds"
- Subtract 1 from Countdown
- Set txt_Countdown to Countdown
- Activate your group of controls
