You should be able to move the 'if Counter.value ...' outside of the
event code but you do have to put it in a loop.

Do

...
if Counter.value ...
...

Loop

There is no implied loop when you get to the end of sub Main() -
processing of the script is finished. Virtual circuits and event code
continues indefinitely.

You really don't want script code in a loop if you can avoid it.
Executing code is not particularly fast on the OOPic.
