boldfish, the way I look at, it you owe me. I've spent way too much time on the puzzler, and I'm at what it claims is the last level and I'm dead stuck. If you'll kindly give me your address, I can send you a bill to cover all of the billable hours that I figure you cost me by posting that link.;-)
There will also be a surcharge for emotional and mental distress caused by being stuck on the level I'm on.
