Why can't I traverse the tuple within the function using the integer variable I created prior to defining the function?

[deal_with_Exceed]

here’s the code:

and here’s what it says

I honestly think this is pretty dumb why I can’t provide a variable, since its basically asking for an integer and I’m giving one to it. Is there any workaround for this? I’m trying to update the playerCarTier by += 1 every time the WinRestart() function is called.

Tuple

Tuples can only specify literals for indexes to ensure that no failures occur.
You can use array type instead.

You can cast your tierlist into an array, provided all entires share a common type and iterate over it instead.
