Hi all, I am having a few probs with the below

print "Content-type: text/html\n\n";

print "<html><head><script="javascript" src="demo.js"</script><title>T
+ESTING</title></head>";

....
<FORM ACTION="expandtree.cgi" METHOD="POST"
ENCTYPE="multipart/form-data">

<div align="left"><br>
<input type="checkbox" name="option1" value="N" checked> N-linked<br>

<SELECT MULTIPLE NAME=demo SIZE=2>
<OPTION VALUE="A1">A1 
<OPTION VALUE="A2">A2 

</SELECT>
<INPUT TYPE=button VALUE="Select All" ONCLICK="selectAll(this.form.dem
+o,true)">
<INPUT TYPE=button VALUE="Clear All" ONCLICK="selectAll(this.form.demo
+,false)">

function selectAll(cbList,bSelect) {
