Hi,
Woah, I am impressed. I watched it and enjoyed it a lot, it was great to see you making your way inside DataMaker and ArrayMaker, for sure this will help a lot of people understanding the power behind these tools.
As for the glitch on missing the hashtable add action, very odd, it's when you switched back to the previous state.
which version of PlayMaker did you used?
Tips: turn off "dim Finished actions" in PlayMaker pref so you can see all actions from all state clearly when debugging.
Thanks
Bye,
Jean
