3. Assign the Variables Constraints:
   1. Click over / Select the Deck
   2. At Properties: Click over / SELECT to Edit the Variable Constraints
   3. Click at the ... (three dots button) to open the Deck Template Window
   4. Click over / Select the Template to check
   5. Click over / Select the Thickness (it will turn to blue)
   6. Change the top window view from Template to Variable to be able to verify the input
   7. Set it as Active (it will have the Checkmark)
