Howard,

Seems to be a problem with the web site. I get to the "Autonumbering -- Introduction" page ok, but after that, whenever I click a pointer/link to any one of the subsections ("Creating the Sequence, Part 1", "Creating the Sequence, Part 2") all I get is Creating the Sequence, Part 1. Using my browser to view the source code for the Introduction page shows that all of these links point to the same page.

Using the "forward" buttons on each page worked to get me through the series.

And thanks to all for the pointers. Received on Mon May 17 2004 - 10:08:33 CDT
