I clicked on "Continue" but I'm stuck on the same page. What's going on?

You've either done too much, or not enough. Check the line that says, "Required: Start Number." Did you enter a start number? It's required! And it's got to be a numeral. If you used letters or words (such as "no" or "one") in that line, just change that to digits. If that's not the problem, double-check that you did not enter too much text on any line. Too much text will result in a pink box indicating which line is to long, and will also appear in red on the proof.
