Thanks for both of your suggestions, and for explaining them so well. It is very helpful for me. Here is my script in case either of you would care to look more. I will try adding in the code you gave me and see how it goes, curbview.
I hope it works ok to upload the script in a Word doc. I thought that pasting the whole code from the page right into the forum window might be a little much. Please let me know if it is more optimal to view another way.
