The last version I worked on was 1.07. I didn't create the beta, and I don't know anything about it. I turned development over to someone else, but he apparently stopped working on it.
I would like to set the selected category as a global variable to avoid access the database on every user click.
So you want to access the variable on different HTTP requests, not merely later on the same HTTP request?
Using a "global" variable won't accomplish that. You'll need to save the variable in one of several ways: in a session, URL parameter, form field or cookie.
Billy, other than that error message, are there any functional problems? Should the release be delayed to resolve this, or is it just a "cosmetic" issue that can be ignored for now?
