if (elm.type == 'checkbox') {

if (re.test(elm.name)) {

elm.checked = false;

А бе ако може и малко обяснение щото като го копирам така кода бачка, ама като го слагам на мойта страница неще.... Кода го слагам в .js файл
чекбоксовете ги вада със цикъл и името им едно и също, и с id-то така, най-много по една цифричка да му вкарам
Код: 
id="chk1"
id="chk2"
id="chk3"
id="chk4"
и т.н.
 
В този случай изобщо не ти трябват ID-тата
Важни са имената.Виж, махнал съм ID-тата и си бачка безотказно.Трябва да направиш всеки чек-бокс с различно име:

Апф.... Точно името не трябва да променям :( Как ше стане да проверява id-то???

Edit: И имети и ИД-ти променям и не бачка
Код: 
<script type="text/javascript" src="'java.js'"></script>
Код: 
<form id="Form1" name="add" action="" method="post" enctype="multipart/form-data" runat="server">
Код: 
   <input type='checkbox' name='type0' value='0' onclick='SingleSelect('chk',this);' id='chk0' /> <span class='fontF1 fontSzBig'>Едностаен</span><br />
 <input type='checkbox' name='type1' value='1' onclick='SingleSelect('chk',this);' id='chk1' /> <span class='fontF1 fontSzBig'>Двустаен</span><br />
