You're welcome!
JavaScript is very sensitive to syntax errors and tends to just stop all execution of JavaScript on the page when an error is detected.
At least, when PHP encounters an error, it generally posts a message highlighting where the issue is.. Only the JavaScript console on your browser would contain the location of the issue .. I'd used Firefox and the error console showed where the issue was. Since that value comes from PHP, it was simple to isolate it to a small problem with the Settings.php entry involved.
