For Next Error

[hcI]

Hello ! First, i'm sorry for my bad english.

So, let's explain. I'm making a little game with AutoIt and, i have some bugs

I just want to say that  $lb_p_sc  is a label who display scores and  $w  have the actual score awaiting to be displayed 1 by 1 every 1/5 seconds (200ms)

here is my code :

Func sys_3($x)
    If $k = 1 Then
        If $x = 0 Then
            $w = $q
            While $w > 0 ; While works perfectly
                Sleep(200)
                $v = GUICtrlRead($lb_p_sc)
                GUICtrlSetData($lb_p_sc, $v + 1)
                $w -= 1
            WEnd
        ElseIf $x = 1 Then
            $w = $r
        ElseIf $x = 2 Then
            $w = $s
        ElseIf $x = 3 Then
            $w = $u
        EndIf
    EndIf
EndFunc

From there, no problem ! Everything work. But when i change While - WEnd to For - Next  everyting are going wrong..

Here is the code with Next - For :

Func sys_3($x)
    If $k = 1 Then
        If $x = 0 Then
            $w = $q
            For $w To 0 Step -1
                Sleep(200)
                $v = GUICtrlRead($lb_p_sc)
                GUICtrlSetData($lb_p_sc, $v + 1)
            Next
        ElseIf $x = 1 Then
            $w = $r
        ElseIf $x = 2 Then
            $w = $s
        ElseIf $x = 3 Then
            $w = $u
        EndIf
    EndIf
EndFunc

And when i try to execute that, it  says so much error but the problem from For - Next (by deduction)

So here's the errors marked  in the console:

I don't understand why For - Next is making so much error.

If someone can tell why (and how to make it right?)

Thanks

Well the syntax for the For statement is wrong and should be : For $w = $q to 0 step -1
Just check the helpfile for proper syntax explanation.

I may be wrong, but if I remember I think your 

For $w To 0 Step -1

needs to be:

For $w=$q To 0 Step -1

at least that's what I see from the documentation. I've never used a for loop without initializing the counter.

[hcI]

Thanks you. it works ! The help on For loop don't explain too much.. So I did like I've understood

Don't blame the writer of the helpfile page for your own mistakes.

The examples are pretty clear.
