Hi Jon-
The general concept looks correct.
Have you put a trace to make sure that your markerArray has a non-0
length and that the for loop actually iterates? Perhaps there was a
problem with scope of the array variable.
If you post a zip with all of the code, then I can try it out and
investigate further.
