Once again, thank you very much. I used the void loop you made for me and it works perfectly. Thank you.
I hope I made it clear enough so you could understand how it was working in case you wanted it to work differently.
Note that these variations all have roughly the same effect:
pos = pos + 1;
pos += 1;
pos++;
++pos;
Typically one would use pos++ for increment and pos-- for decrement but I used the slightly more verbose "pos += 1" and "pos -= 1" to be more explicit.
