also it's document.whatever.value
But even this moght not work depending on where in the DOM the element is located. give the element in id and the do document.getElementById(id).value
eg:
Code:
<input type="radio" value="Right" name="algin" id="myID">
<input type="Button" onclick="alert(document.getElementById('myID').value)" value="Submit" name="B1" size="20">

It's Always Show "Left"
Code:
<span lang="en-us"><font face="Tahoma" size="2"> </font></span><font face="Tahoma"><input type="radio" value="Left" name="algin" id="myID" checked><span lang="en-us"><font size="2">Left</font></span></font></p>
<p>
<font face="Tahoma"><span lang="en-us"><font size="2"> </font></span><input type="radio" value="Right " name="algin" ><span lang="en-us"><font size="2">
Right</font></span></font></p>
<p><input type="Button" onclick="alert(document.getElementById('myID').value)" value="Submit" name="B1" size="20">

well, of course it will always show left. you've given the ID to the tag with value="Left". Note that no two elements can have the same ID attribute.
