Thanks for everyone your feedback. While messing around with that
extra variable "num1" I was doing this:

while [ $1 -le $2 ]
  echo $1
  num1=$(( $1 + 1 )) #I'm afraid num1=$(( $1 ++ )) doesn't work.

...Which was why it wasn't working, duh :p  Now it works fine :)

:) Tell me about it!   I'm still getting used to stuff like parameter
expansion.  It's one of those things that you read, do it wrong
anyway; re-read and do correctly the next few tries; then suddenly
forget, make the same mistake and wonder why it doesn't work.

Me too.  It's the first time I've seen the "let" command.
