I remember now. I knew it was something simple and really stupid. As it turns out, the problem here is that this error is NOT consistent. Most of the time you don't need to worry about what you name your variables and session variables. But every once in a while if you are in the habit of naming variables the same name as session variable (as I do), then the practice sometimes generates an error. So to solve the above problem, all you have to do is use a different variable name than the session name for that instance -- something like: session_start(); $_SESSION['session_test'] = null; $test = 1; But like I said, the error is only generated every once in a while and NOT consistently. As such, you may have scores of variables that match scores of sessions with no errors. But then you add just one more and bingo you have an error that leaves you thinking "What the Hell just happened?" What is further maddening is that after you fix that error, by changing then name of that conflict, you can go back to naming as you like until another error is generated. It happens only once in a while and not always. Thanks for loaning me your memory. Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
