Hello Listers, I have been trying to thank those of you who responded to my request for suggestions on the above. I did receive several replies and I did find them most helpful. I tried to thank each of you indivually and via the List. However, for some reason my list mail has bounced. Robin is working on it and asked me to try writing to the list again. In any case, thank you all very much. Margaret Bence Davis --------------------------------- Do you Yahoo!? Protect your identity with Yahoo! Mail AddressGuard
