Having trouble with multiple frames and switching data between them.

[Jumpercable]

Hi guys, my names Jumpercable, author of EZ Mount addon.

Ive been trying to find a way to add options to my addon using: InterfaceOptions_AddCategory()

Im struggling to get the SavedVariablesPerChar into the options frame, and then any changes saved back when the player_logout event fires ( my belief is that it should auto write the savedvariables per char without any extra code ).

The purpose of this is to let me load the savedvariablespercharacter and update the options frame based on saved variables. If the options are changed the variables are saved on logout. The slash command is what my addon uses to run from an ingame macro.
Heres some code ive being trying to work with before adding it into my addon:
Any advice here or if i can even do this, any help is appreciated.

local EZTest_Main = CreateFrame("Frame","EZTest")
local EZTest      = CreateFrame("Button","EZTest",EZTest_Main,"SecureActionButtonTemplate")


EZTest:RegisterEvent("PLAYER_LOGIN")
EZTest:SetScript("OnEvent", function(self,event,...)
    if type(EZTestData) ~= "table" then
      print(type(EZTestData))
      EZTestData = {}
      EZTestData.Config_Flying = 0
      EZTestData.Config_Dismount = 0
      ChatFrame1:AddMessage('EZ Mount: Initial variables set for '..UnitName("player"))
    else
      print(EZTestData.Config_Flying, EZTestData.Config_Dismount)
      if not EZTestData.Config_Flying then
        EZTestData.Config_Flying = 0
        ChatFrame1:AddMessage('Empty Data for Flying')
      else
        if EZTestData.Config_Flying == 0 then
          ChatFrame1:AddMessage('No flying')
        else
          ChatFrame1:AddMessage('Flying')
        end
      end
		  if not EZTestData.Config_Dismount then
        EZTestData.Config_Dismount = 0
        ChatFrame1:AddMessage('Empty Data for Dismount')
      else
        if EZTestData.Config_Dismount == 0 then
          ChatFrame1:AddMessage('No Dismount')
        else
          ChatFrame1:AddMessage('Dismount')
        end
      end
	end
  Create_GUI()
end)

SLASH_EZTEST1 = "/EZTest"
SlashCmdList["EZTest"] = function(msg)
  print(EZTestData.Config_Flying,' Config Variable')  
end
