Hi Goran-
Did you figure it out? It might be simpler for you to put the loading
outside of the makePolygon function, and just pass the XML into the
makePolygon function. Then you wouldn't need to deal with the asynchronous
nature.
If you still need help, please send over the full code for me to experiment
with.
