Appreciate the response! This does get me to the point where I can display the Growth Rate for a specific class or actor, and that's great! But I'm having difficulty translating that to the menu where it would need to display the current rate for the selected character.
For example I can set the displayed parameter to my Mage class, but when opening the same menu for my Knight, it will still display the Mage class parameters because the code isn't there to change the parameters to Knight.
Edit: Nevermind! By declaring a constant I was able to replace the actor ID with "user" and it now displays accurately. Thank you for the help and the awesome plugin!
