Tony,
Look at the code for the wx13.php page. You will see something like this:
<FORM
ACTION="../cgi-bin/redirect.pl"
METHOD=POST onSubmit="return dropdown(this.gourl)">
<SELECT NAME="gourl">
<OPTION VALUE="">Choose a Month...
<OPTION VALUE="scripts/climatedataout12008.html">January 2008
<OPTION VALUE="scripts/climatedataout22008.html">Febuary 2008
<OPTION VALUE="scripts/climatedataout32008.html">March 2008
<OPTION VALUE="scripts/climatedataout42008.html">April 2008
<OPTION VALUE="scripts/climatedataout52008.html">May 2008
<OPTION VALUE="scripts/climatedataout62008.html">June 2008
<OPTION VALUE="scripts/climatedataout72008.html">July 2008
<OPTION VALUE="scripts/climatedataout82008.html">August 2008
</SELECT>
<INPUT TYPE=SUBMIT VALUE="Go">
</FORM>
Just add the link there. Maybe something like:
<OPTION VALUE="scripts/climatedataout.html">Current Month
See if that is what you are trying to do?
