You need to split the value into an array using php, then list it out.
Lots of ways to do that, here's one.
$result4 = mysql_query( "SELECT DCD_Access FROM userdb WHERE ID =
'$user_ID'");
$DCD = mysql_fetch_array ( $result4 );
print " <td width='6%' valign=top>\n
<div align='center'>\n
<select name='LCompare'>\n
<option value='none'>None</option>\n
<option value='within'>Within Gel</option>\n";
// new stuff
$vals= explode(", ", $DCD["DCD_Access"]);
for ($i=0;$i<count($vals);$i++) {
print "<option value='$vals[$i]'>$vals[$i]</option>\n";
}
// end new stuff
print " </select></div>\n
</td>\n";
