I am sure someone had thought about this harder and > longer than I did. How about setting it up as a different script type as well. <script type="text/javascript+click"> That may be a horrible idea. So lets focus on the concern. I'd like to be able to embed things like this in an HTML page and have them not break the page for browsers that don't support the template tag. This script could pop up an error onload about how event doesn't have any attributes. Possibly, anyway. -Charles
