Refresh page Script - stop/start toggle button

[bayswater]

1) Script Title: Refresh page Script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex6/refresh.htm

3) Describe problem:
Is there a way to insert a stop-button or stop-link that you could toggle between "Stop countdown" and "Restart countdown"? I can't quite figure that out...
