That makes sense, I can see why it would be needed - thanks for letting us know the solution.


As you now have it sorted out, could you please do us a little favour, and mark the thread as Resolved?
(this saves time reading for those of us who like to answer questions, and also helps those who search to find answers)

You can do it by clicking on "Thread tools" just above the first post in this thread, then "Mark thread resolved". (like various other features of this site, you need JavaScript enabled in your browser for this to work).
