You're welcome. Glad to help out. Thanks for the feedback and the rep. I think it would be best for you to start a new thread for the change event question and mark this thread as solved. See Forum Rule 9 below.

9. Acknowledge the responses you receive, good or bad. If your problem is solved, please say so clearly, and mark your thread as Solved: Click Thread Tools above your first post, select "Mark your thread as Solved". Or click the Edit button on your first post in the thread, Click Go Advanced, select [SOLVED] from the Prefix dropdown, then click Save Changes. If more than two days have elapsed, the Dropdown option or Edit button will not appear -- ask a moderator to mark it.
