for each chckbox in checkboxarr

DName= chckbox.DataContext.Name
log.Message DName
CState= chckbox.wState
Log.Message CState
if (DName= "Disc Configuration # 2" and CState=0) then
chckbox.Click
BoolCheck=True
'else
set PanelViewer = Aliases.T701_Volcano.HwndSource_ShellView.ShellView.DockTGP.ScrlViewer
Panelarr = PanelViewer.FindAllChildren(Array("ClrClassName"),Array("Expander"),500)
