First make sure that you have your Script Toolbar checked

In your Palettes be sure that "Script Output" is checked



Save your new scripts in your "Scripts-Restricted" folder   

If there are extra plug-ins needed for the script store them in
your "plugins" folder

Open your graphic or tube and choose the script you want to run

Click on the  arrow to run the script. 

You can click on the "Toggle Execution Mode" and the script will stop at every step and you will need to click on the arrow again to go to the next step

Some scripts run straight through but most give you directions on what to do next.

Make sure your "Script Output" is open  as pictured below and follow the directions there and in the popups

If the script is a "Pause" script you will need to click the arrow beside the script title box to go to the next step.
