You cannot use "foo[0]" as the name of your form element, because JavaScript doesn't work that way. JS would think of "foo[0]" as the name of the element, or the name of an object holding an array of elements, which is not your case. Anyway, you can loop thru all your form elements, and get their names from them. You can also check for specific form element types if you only need all text field elements, or anything like that. Here goes some code : <SCRIPT LANGUAGE="JavaScript"> <!-- for (var i = 0; i < document.form_name.elements.length; i++) { if (document.form_name.elements[i].type == "text") { alert("name of element = " + document.form_name.elements[i].name); alert("value of element = " + document.form_name.elements[i].value); } } //--> </SCRIPT> Regards, Joao -- Joao Prado Maia Web Developer Kefta, Inc.
