questions about functions

[faustf]

hi guys  i have  this function

Func _Indietro_foto($input_readBK, $listJPGreload)

    Local $path_jpg = GUICtrlRead($input_readBK)
    ;MsgBox(0,'3178',$path_jpg)
    Local $aJpg_repath = StringSplit($path_jpg, "\")
    Local $aPath[1][($aJpg_repath[0]) * 2]
    Local $l = 0

    For $y = 1 To (UBound($aJpg_repath) - 1) - 1
        $aPath[0][$l] = $aJpg_repath[$y]
        $l += 1
        $aPath[0][$l] = "\"
        $l += 1
    Next
    ;_ArrayDisplay($aPath)
    Local $sPath_back = _ArrayToString($aPath, "")
    GUICtrlSetData($input_readBK, $sPath_back)
    ;_FileJPG_reload()
    Select
        Case $iGCTRL_ClickNewItemB56 = 1
            GUICtrlDelete($SITIWEB_NewItem_List2)
            $SITIWEB_NewItem_List2 = _ListView_OK("", 552, 166, 377, 266, "Descrizione_370")

        Case $CTRL_Clicked_MultyeBayB56 = 1
            GUICtrlDelete($SITIWEB_NIMLTY_eBay_List2)
            $SITIWEB_NIMLTY_eBay_List2 = _ListView_OK("", 799, 146, 377, 279, "Descrizione_370")

    EndSelect
    _FileJPG_reload($input_readBK, $listJPGreload)
    _Disabilita_X_Condurre_3("Enable")

EndFunc   ;==>_Indietro_foto

when i call  it

like     _Indietro_foto($SITIWEB_NewItem_Input5, $SITIWEB_NewItem_List2)

it  tell me error 

"C:\_GESTIONALE_NEW\include\GUI_Configure.au3" (1571) : ==> Variable used without being declared.:
Local $path_jpg = GUICtrlRead($input_readBK)
Local $path_jpg = GUICtrlRead(^ ERROR

why ???

Because you probably declared it into another function. You have to declare it as a global variable (at the beginning)

the variable  , $SITIWEB_NewItem_Input5, $SITIWEB_NewItem_List2    is global

and 

$input_readBK

  is unique o_O , never declared before

[jguinch]

Can you show us the part of code where _Indietro_foto is called ?

[faustf]

yea is there a problem i  call directly a function without a variable , Sorrry

some time i am very  slowwww

I think you don't take enough time to search by yourself. You take the easy way by asking here, so you learn slowly. We learn from our mistakes.

_Indietro_foto
