Autoit error Variable subscript badly formatted

[Dalinou]

Hello I'm Dalinou, I want to create a sudoku résolveur but when I finish my progrmm, I have an error what I don't understand where it comming and why it is here.

The error is this ""C:\Users\Gwendal\Desktop\sudoku.au3" (97) : ==> Variable subscript badly formatted.:
If $sudoku[$L][$C] Then $a = $a + 1
If $sudoku[$L][^ ERROR"

This is the progrmme:

Somebody can help me, please ???

Thank you

Welcome to AutoIt and the forum!
Are you sure that $L and $C contain valid numeic values?

Hi @Dalinou.

On line 96 you call "NeufToTrois" with "$C" as argument. When looking into the function, you have a switch with 3 identical cases. Nowhere does it handle if number is less than 1 or more than 3. When i run your code "$C" is equals 4. so "NeufToTrois" returns "" (nothing) so we get $j+3*(""-1) and $j is equals 1 so the result is -2
