I've studied the code of the demo pages and I can't see any difference between that and my own (my own implementation is built using the zip download, unmodified!)
The stars get created fine, but each one has it's "value" displayed above it - where the same code on the example page does not do this? I'm a bit stumped, can anyone think of what might cause this. Sorry I can't post a URL currently... but hopefully my explanation of whats happening might trigger someones thoughts? Cheers, Rob
