Thanks to everyone. I have my problem solved. No matter what value I assigned to the checked property, it always checked the box. I tried "FALSE", "false", "OFF", "off", "0", & "unchecked". They all turned the check box ON.What I came up with is this: if (document.Register.T2B.checked) { document.Register.T2B.click(); }Basicly, I check to see if the box is checked, and if it is, I issue the click() command to uncheck it.
