[REBOL] Even I make mistakes<g>

If anyone tried to order either REBOL FOR DUMMIES or REBOL: THE OFFICIAL
GUIDE yesterday, you found your order would not go through, even with all
the correct information. Why? Even I flub up on occasion. The forms are now
fixed and orders go though fine.
The mistake was a dumb one (as opposed to a Dummies one) and I reveal it
since you may find such instructive in your own coding. I wrote this really
slick little credit card validation function (published earlier on this
list) Saturday. Tested it rigorously, and it worked fine. So I dropped it
into the order forms; tested them briefly; all seemed fine; so I went live
with the changes. Then I get e-mail this morning from a couple of people who
tried to order books yesterday and the orders would not record. Here's the
mistake! One of the REBOL words I defined in my credit card validation
function was the same as one in my form processing script (but the words, of
course, did different functions). This mismatch did not crash the script
(such would have pointed to an obvious problem) but rather caused a more
subtle misoperation; i.e. orders would not record.
The moral of this tale? Document! I stress that in REBOL FOR DUMMIES. If you
don't document, scripts sometimes will coil around and bite you on the ....
well, anyway, I fixed it<g>.
