I have an old table that code has worked. However when trying to execute commands that begin with trainer.XXX, I get an Access violation. The code compiles without error and I'll attach a partial bit of the code.

Code:

function trainer:start()
self.form = createForm(false); -- self = trainer since it's a function inside of a table...
setProperty(self.form , "BiDiMode", "bdLeftToRight");
self.form.Caption = 'Cheat Panel';
self.form.Width = 420;
self.form.Height = 420;
self.form.Left = 385;
self.form.Top =7;
.......
self.value_panel3 = createPanel(self.form);
self.value_panel3.Caption = '';
self.value_panel3.left = 240;
self.value_panel3.top = 130;
self.value_panel3.Height = 35;
self.value_panel3.Width = 90;--Extra Exp
--
self.value_panel4 = createPanel(self.form);
self.value_panel4.Caption = '';
self.value_panel4.left = 240;
self.value_panel4.top = 170;
self.value_panel4.Height = 35;
self.value_panel4.Width = 90;--Extra Ap
--
self.extra_ap_value = createEdit(self.value_panel4);
self.extra_ap_value.top = 4;
self.extra_ap_value.left = 2;
self.extra_ap_value.Width = 86;
self.extra_ap_value.Height = 33;
local keynr = string.byte(key); if (keynr~=8) and (keynr~=45) and (keynr~=13) and ((keynr<48) or (keynr>57)) then key=nil; end if (keynr==13 and not(sender.Caption == nil or sender.Caption == '')) then key = nil; self.set_exp.onClick(); end return key; end)
--
self.extra_exp_value = createEdit(self.value_panel3);
self.extra_exp_value.top = 4;
self.extra_exp_value.left = 2;
self.extra_exp_value.Width = 86;
self.extra_exp_value.Height = 33;
local keynr = string.byte(key); if (keynr~=8) and (keynr~=45) and (keynr~=13) and ((keynr<48) or (keynr>57)) then key=nil; end if (keynr==13 and not(sender.Caption == nil or sender.Caption == '')) then key = nil; self.set_exp.onClick(); end return key; end)
--
function ExtraExp(sender)
local AL = getAddressList();
-- if not valueE then
valueE = tonumber(trainer.extra_exp_value.Text);
--print(valueE)
-- end;
-- if not valueA then
valueA = tonumber(trainer.extra_ap_value.Text);
--print(valueA)
-- end;
if tonumber(addresslist_getMemoryRecordByDescription(AL, "Battle Byte").Value) == 32 then
if valueE then
addresslist_getMemoryRecordByDescription(AL, "After Battle Non Kill XP").Value = valueE
end;
if valueA then
addresslist_getMemoryRecordByDescription(AL, "After Battle AP").Value = tonumber(valueA)
end;
end;
end
--

valueE = tonumber(trainer.extra_exp_value.Text); gives the Access violation
valueA = tonumber(trainer.extra_ap_value.Text); gives the Access violation

Code:

self.characters_rg = createRadioGroup(self.form);
self.characters_rg.height = 250;
self.characters_rg.width = 90;
self.characters_rg.top = 90;
self.characters_rg.left = 5;
for character,_ in pairs(self.Data.Characters) do
if tonumber(character) then
self.characters_rg.getItems().add(_);
end
end

Further forward in the code
trainer.characters_rg.setItemIndex( Cool

gives the same Access violation

Code:

self.form.show();
print("God mode is not enabled");
print("The table needs to be recalculated");
end--trainer
--
trainer:start();

Any ideas why the code that used to work, now is an Access violation?

Code:

valueE = tonumber(trainer.extra_exp_value.Text);
valueA = tonumber(trainer.extra_ap_value.Text);

-- use
valueE = tonumber(self.extra_exp_value.Text);
valueA = tonumber(self.extra_ap_value.Text);

and

Code:

local self = { }

function trainer_start()
self.form = createForm(false);
...
end

trainer_start()

The procedure call is after the initial compilation and I have had problems using self. That being said I will give it a try and report back.

ETA: I changed the code to self and all works well thanks.
