G'rrrr -- not this old chestnut again! It only "screws up" your JavaScript if you don't write your JavaScript to allow for it. It's really very simple: *by* *definition* in JavaScript, the notation a.b is *identical* to a["b"] Thus, if you have a single checkbox named with name="system", then you can access it in either of these ways: document.form.system document.form["system"] By extension, if you have multiple checkboxes all named with name="system[]", you can refer to them as: document.form["system[]"][0] document.form["system[]"][1] document.form["system[]"][2] etc... I know this works because I've been using it for years (even before I started programming with PHP!). Cheers!
