How to click buttons though loop.

hi

following is my function

Function mo_ChkParamList( lst_no )    

  ExcelDriverPath1="D:\Perforce\ISCP_Main\Projects\ISCP_Test\Test\CardDesigner_New\ELEMENT_VariousViewerAndEditors\Stores\DB_CardParameterList1.xls"

  Call DDT.ExcelDriver(ExcelDriverPath1,"Sheet1")

  Dim parameterName  

  While Not DDT.CurrentDriver.EOF  

   if DDT.CurrentDriver.Value("tab") <> "" then

        tabName=DDT.CurrentDriver.Value("tab")

       Log.message "#####   TAB '"&tabName&"'   #####"

        Call Aliases.CardDesigner.editors.CardParameter.tab_CardParameter.ClickTab(tabName)        

   end if

    parameterName=DDT.CurrentDriver.Value("Param_name")

    log.message Aliases.CardDesigner.editors.CardParameter.WaitVBObject(parameterName,1000).Exists                                    

      if DDT.CurrentDriver.Value("def_undef"&lst_no)= "visible" and Aliases.CardDesigner.editors.CardParameter.WaitVBObject(parameterName,5000).Exists then

        Log.Event"Correct Status Parameter '"&DDT.CurrentDriver.Value("Parameter")&"' is set to "& DDT.CurrentDriver.Value("def_undef"&lst_no)         

      elseif DDT.CurrentDriver.Value("def_undef"&lst_no)= "invisible" and Not Aliases.CardDesigner.editors.CardParameter.WaitVBObject(parameterName,1000).Exists then

        Log.Event"Parameter '"&DDT.CurrentDriver.Value("Parameter")&"' is set to "& DDT.CurrentDriver.Value("def_undef"&lst_no)

      End if                

  Call  DDT.CurrentDriver.Next()

  WEnd

  DDT.CloseDriver(DDT.CurrentDriver.Name)

 

End function



//calling it as follows

mo_ChkParamList 1



error line is



Aliases.CardDesigner.editors.CardParameter.WaitVBObject(parameterName,1000).Exists   

every time it returns False even when object exists on screen while my object names are mentioned in excel file and i am concatinating it with rest of the mapped name.

Excel file is attached.
