Cool idea - never would have thought of this use of a select. Cool.
Here's a version that appears to work.
<SCRIPT TYPE="text/javascript" LANGUAGE=JAVASCRIPT>
<!--
function selectall() {
for ( i=0;
i<document.forms[0].subject.options.length;
i++){
document.forms[0].subject.options[i].selected = true;
}
}
//-->
</SCRIPT>
<FORM>
<SELECT NAME="subject" SIZE=4 MULTIPLE>
<OPTION>First</OPTION>
<OPTION>Second</OPTION>
<OPTION>Third</OPTION>
<OPTION>Fourth</OPTION>
</SELECT>
<INPUT TYPE="button" ONCLICK="selectall()" VALUE="Select All">
</FORM>
