Hello, i have this code

 

Func Minuta () 

   if (TimerDiff($time1)>1000) then
            While $radek<="255"
            local $index=_GUICtrlListView_FindText( $packetwindow, $radek) 
            local $cas=_GUICtrlListView_GetItemText($packetwindow,$index , 2) 
            _GUICtrlListView_SetItemText($packetwindow, $index, Abs($cas+"1"), 2) 
            $radek+=1
            _GUICtrlListView_EnsureVisible($packetwindow, $index)
            if $cas>"50" Then
            ConsoleWrite($cas & @CRLF)
            
            EndIf
         Wend
         $radek = "0"
         $time1=TimerInit()


    endif
EndFunc

I have 2 problems with this code.
1.  Every cycle i want +1 to number but its make +2 or +3  have no idea why
2.  I want write to concele numbers bigger than 50 but it write to console specificly numbers 6,7,8 than 50-99 than 500-999 O.o Have no idea why.

Pls. do you know what happening here?

Hi Nnet, welcome to the forum.

Things that stand out for me.

{1} When you quote a number, you are really saying that number is a string. I suggest you don't do that in this instance, so get rid of the double quotes.

{2} You should declare $radek (i.e. Global $radek at the start of your script).

{3} You really shouldn't keep declaring the Locals all the time inside your loop. Declare them once, before the loop.

{4} I am a bit lost as to what all your code is doing, but then I don't know what $packetwindow is etc, and which number are you referring to - $radek or $cas ?

{5} Obviously there is more code than what you provided, and perhaps we need an overall description of what you are trying to do.
