I tried the simple loop, but it didn't want to run more than once. Of course, I just tried to pause for six hours, then run again. Absolutely did not work.
I will try the more complicated script and see how that works out. Dissappointed that this ties up FM on the computer though - I get an hour-glass during the running of the script, so that's one copy that is out of the running.
Thank you very much for your help, and I'll let you know how it works out!
