Ah the 20 at the start confused me. I tried a few times I get the thrid keypad and it just stays full and doesn't clear or goto the next screen. Good idea, just a bit more polish.
The 20 is a complete mistake, it shouldn't have been there lol. I couldn't figure out how to make the third keypad bar work as it's a negative number. I have now figured it out, but too late for the jam! Definitely needs more polish! Thanks again X
