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.

Make sure brain is in gear before opening mouth!
Remember, what is not said, can be just as important as what is said.
