Thanks again, woddakota but unfortunately the capx wouldn't work for me.
However I was able to see what you have done which helped. I also downloaded the other 2 samples in this thread and between the 3 of them I think I now have a good understanding of how webstores work.
The thing that still confuses me though is how to get the value from the 'Score' over to the 'Best Score' webstore when you die in the game? The game scores correctly now but I want it to remember your score when you die and also update that best score if you manage to beat it on another try... If anyone knows how to do that, please tell me!
