Attribute for <LABEL ...>
FOR = "text string"

If the form element that should be associated with the text in <LABEL ...> can't be contained within <LABEL ...>, such as when the form element in another table cell, use FOR. The value of FOR is the ID of the form element. Note that it is not the name of the field (as given with the NAME attribute) it is the ID as given with the ID attribute. So, for example, this code associates the text "join mailing list?" with the checkbox field that has the ID "joinlist":

This code:

<TABLE BORDER=1 CELLPADDING=5>
<TR> <TD><LABEL FOR="joinlist">join mailing list?</LABEL></TD>
     <TD><INPUT TYPE=CHECKBOX NAME="joinlist" ID="joinlist"></TD>
     </TR>
</TABLE>

produces this:
