Setup, table with a RadioGroup selecting characters, once selected a listview is supposed to display level/Exp. Partial code.

Changing just the code suggestion.

Neither, it is a byte referring to profession and professions have different lvl/exp as the table of values.
I borrowed this table not the code from here I think. The author did a good job in finding/labelling the record. I assumed through searches the professions, exp levels that the professions had the characteristics shown in my code, however, that was/is totally wrong. There are 16 professions, 8 male 8 female, that have different lvl/exp. My table was correct values in the wrong lines.
The professions go like this:
Hero(0)
Wizard(1)
Pilgrim(2)
Sage(3)
Soldier(4)
Merchant(5)
Fighter(6)
Goof Off(7)
These are males, add 8 to get females. So I rebuilt the code with that in mind and ran into a hornets nest.
The first error was the characters gave me errors closing the "{" after the first 8. Cutting the professions to eight allowed the code to be complied.
I'll post the new data section and old, not working now radio graph. I sill have the same error,
the prof is 0
The hero name is Hero 1
Error:[string "trainer = {
..."]:581: bad argument #1 to 'pairs' (table expected, got nil)
When selecting the other 3 characters the listview is populated with still the wrong data, but I stopped working on that sometime ago. I believe I'll be able to display the correct values, but the error on Hero1 has me puzzle.

Warning;
You don't have a main table called "self"!
The main table name of the lists you use is "trainer".
I corrected the following sections in your code:

Several questions,

[AylinCE]

If you copied the entire sample code I gave and tried it in the lua table, you would have used the following lines.

[Dark Byte]

Here's a version with a slight performance improvement:

[AylinCE]

[bknight2602]

You noted that you had entered the appropriate code, so I looked at the radiogroup only. My bad
After entering the code, nothing worked.
Moved createlistview before radiogroup deleted the example self.edit_1.Text = "3" an specific example, not general. In terms of setting it to prof, well your suggestion is prof = self.edit_1.Text, but self.edit_1.Text hasn't been set yet, remember createlistview is before createradiogroup, currently.
So I added into createradiogroup

[AylinCE]

1) Continue with @DarkByte code.
Copy the code and run it as is.

2) In the form, type numbers 1-17 in the edit1 box and select a hero from the RadioGroup.

3) In this case, "prof" gets the index from edit1 and reflects it in the list box.

What value does the following address give for "prof" in your case?

[bknight2602]

I get no code from the link, so I assume that the code you provided after Db's post is the code.
You indicate copy it and then paste it. Where in my code and does it replace some of my code?
Further your question, what does

[AylinCE]

[bknight2602]

The title was loading the correct table values. However, that might be accomplished.
I'm sure that the code you presented works. Thanks for your input.

One more error
