ITERATE=240
for COUNT in `seq -w 1 $TOTAL`
do
  OTHER=$(($COUNT*2))
  ... more stuff
  ...
done

The problem I am having is that I can't figure out how to multiply COUNT by 2. In this example since TOTAL is 240, COUNT will be 3 digits. I get an error message at count 8 saying the value is too great for the base, which I assume is because of 3 digits and something with binary.

Is there a way I can multiply this number by two, while still interating through by one?

Don't use the -w option on seq. Many things interpret numbers starting with 0 as octal (base 8), likewise with 0x and hexadecimal (base 16).

I need the -w option to keep the 000 spaces in front of the number. Is there another clean way to do this?

try this:
previously declare variable OTHER and set it to 0 then in the loop:

let OTHER="$COUNT"*2
