Multiple Fields on single mouse click

Multiple Fields on single mouse click

I need to get the clicked on field plus another field in the current row of a table....

$(function() {
           $(".trclick").live("click", function() {
             $("#flightno").val($(this).text());  //.children("a").text());
           });
        })

Here is the table code:

echo("<td class='tdclick'><a href='#'>$fnum</a>");
echo("<td>$tail</td>");
echo("<td>$stdate</td>");
echo("<td class='trclick'><center><a href='#'>$rev</a></center></td></tr>");

The class of a column in the table is assigned the class - trclick.   I need to get the value of $fnum when the $rev field is clicked.  How can I get the value of $fnum when $rev is clicked?

Thanks,
Bill S.
