Hi John, yes I only need to change the order of the slides. I started out yesterday using the move command, but when I ran the script all the slides were still in the wrong order - not where I specified them to go. Perhaps I was using the command incorrectly, but the reason that I wanted to just keep changing the value of S and carrying out a function on the new value was so that I could have something like:

s=20
s=8
s=5

etc all in a line. I have to change the order several times, and it is very time consuming to keep typing the number of the slides in the brackets every time I needed to change the order for a new presentation.
