Actually, Zen-Cart does even better than that, as you DON'T have to add the call to it. Once inside you js folder just add: jscript_ the the name of your file, and Zen will automatically load it for you. In other words, if you have a jquery file named "jquery.js", you would just put it in your js folder, renaming it to "jscript_jquery.js". That's it. Zen will do the rest. So ANY javascript file...........no matter what the name.............just add the: "jscript_" to the beginning of the name................easy, huh?

Hope this helps.
