Well, the main problem is that you used server side events instead of client side:
onResourceStart instead of onClientResourceStart
onMarkerHit instead of onClientMarkerHit
onMarkerLeave instead of onClientMarkerLeave
Also, the event handlers for each button had to be inside the function where you create them.
And, you we're setting alpha of non-existent elements, you forgot to rename it when you renamed button variables.
theMarker = createMarker ( 295.83984375, -80.8115234375, 1001.515625, "cylinder", 1.5, 255, 255, 0, 0 )

You really should start using debugscript.
