Thanks to both of you for the come back. Yal, your diagnosis was not what I wanted to hear, but was certainly what I needed to know. Pete, while your advice was certainly more encouraging, the job may be beyond my skill level. Despite this, I will check it out. Unfortunately, I have to go out of town and probably won't be able to get back to this for about a week. I hope you will both be watching the forum at that time in case I need to ask another question. Thank you, thank you, thank you!
