Veronica's SESSION Demo (Page 1)

This demo page adds one to a numeric variable and stores that value in a SESSION.
This could be used to give users an option to flip through choices.
The numeric variable in this example refers to one of twelve categories of furniture (from an array).
Click ~GOTO Page 2~ to see that the values are carried over.

The following shows the current values in this SESSION.
