probably some small stupid error I'm not seeing (printing text for numbers)

hi,
this is not working and I'm stumped. I'm guessing it's something small (I hope)and I'm just worn out with it. up till 11 works, then suddenly at 12 and beyond not (it just prints 12 * $1 ) instead of 1 * $10 and 2 * $1.
thanks.

(usernumber % 10 == 1)

works only for the number 11 since you explicitely compare against the 1 (and not 2 etc.). Change to:

(usernumber % 10 != 0)


Note that the last if has no effect since everything can be divided by 1.
