Christmas Bird Count history report system

The top-level Web page will display a form with a set of radiobuttons, one for each U.S. state and Canadian province, plus one circle near Newfoundland that is actually French territory (St. Pierre and Miquelon).

To minimize screen height, these regional radiobuttons are presented in columns.

This form also displays two fields labeled First year no. and Last year no. that the user can use to limit the time range when searching for efforts in the selected region.

The submit button is entitled Generate a regional index.

Here's an outline of the generated XHTML in the body section (excluding the content added by the tccpage2 module).
