How set variables triggers edx QlikView 11

[#1]

I need to set the value of a variable trigger.

I must to set variable (es exvariable = " CH1000")

I can not set up correctly

"TriggerEDXTask (new GUID (), 'reloadQlikView', "ReloadPassword", "vFileName", parameterList);"

I write macros that use:set variables in triggers edx QlikView 11

Sub TriggerEDX(task,password,toRefresh,export,percorsoQv)  

    Dim objHttp

    Dim strUrl

    Dim strData

    Dim strKeyRequest

    Dim strKeyAwnser

    Dim strTaskName

    strTaskName = task

    Dim strTaskPassword

    strTaskPassword = password

        Dim strChartID

    strChartID = ChartID

    call toRefresh_value(toRefresh,export,percorsoQvd,"")        

    call ExportType(export,percorsoQvd,"CH376")                    

    set shl = createobject("wscript.shell")

    strServer = "http://xxx:4799/QMS/Service"

    call shl.Run ("\\xxx\QMSEDX\QMSEDX.exe -task="&strTaskName&" -qms="& Chr(34) & strServer & Chr(34) -ChartID="11" ,0,True) 

End Sub

sub LOAD

    set pqb = ActiveDocument.GetVariable("percorsoQvd")

    percorsoQvd = pqb.GetContent.String

    export = "Server"    'working on server

    set nt = ActiveDocument.GetVariable("nomeTask")

    nomeTask = nt.GetContent.String

    call TriggerEDX(nomeTask,"ZZZ","XXX",export,percorsoQvd)

  end sub
