Why array-style names won't work with Javascript is actually quite logical. If you take: <input type="text" name="Settings[Name]"> as an example, then this JavaScript code: document.forms.FormNameHere.elements.Settings[Name].value won't work, of course! Name is an undefined constant in this case, as it's interpreted as a constant, not as a string... But adding quotes won't help you: document.forms.FormNameHere.elements.Settings["Name"].value Since the name="Settings[Name]" in the tag won't result in a "Settings"-subarray of the form.FormNameHere.elements array in the DOM. The solution? Use this: document.forms.FormNameHere.elements["Settings[Name]"].value "Settings[Name]" is looked up in the elements array, and is found... The elements array is a hash, so strings can be used as keys! -- http://www.php.net/manual/en/language.types.array.php http://master.php.net/manage/user-notes.php?action=edit+26121 http://master.php.net/manage/user-notes.php?action=delete+26121 http://master.php.net/manage/user-notes.php?action=reject+26121
