Hi there!
Nice you manage to got it working! And don't need to be sorry. I'm here to help you :D
I just want to point out what was causing the error for you to know( and maybe someone else):
There is (or was) a custom type of parameter set on the parameter list. But, you are not using the Custom Parameter plugin as you shown on your plugin list. As so, the plugin was throwing an error because it was not finding the method set on Game_Actor created by the Custom Parameter plugin.
That is one of the reasons why it is important for you to try to build the plugin parameter yourself than just copy and paste.
But I'm happy for the 5 stars, almost anyone give rates.
Thanks a lot! Happy Rpg Making!
