dropdown dates menu

hello

i have a cold fusion page which has a bunch of drop down menus which on selection executes a javascript on the cold fusion page and displays the relevant info.

For ex:
ddown menu:campus -

<%
fp_sQry="SELECT Campus ID, CampusName + ' ' + CampusType as Campus FROM Table WHERE CampusType = 'Great School' ORDER BY CampusName + ' ' + CampusType"
fp_sDefault=""
fp_sNoRecords="No records returned."
fp_sDataConn="Data_Conn"
fp_iMaxRecords=0
fp_iCommandType=1
fp_iPageSize=0
fp_fTableFormat=False
fp_fMenuFormat=True
fp_sMenuChoice="Campus"
fp_sMenuValue="CampusID"
fp_iDisplayCols=2
fp_fCustomQuery=True
BOTID=1
fp_iRegion=BOTID
%>
<!--webbot bot="DatabaseRegionStart" endspan --><select NAME="CampusID" SIZE="1">
<option selected value="00000">Select Campus ...</option>
<!--webbot bot="AspInclude" clientside u-incfile="_fpclass/fpdbrgn1.inc" startspan --><!--#include file="_fpclass/fpdbrgn1.inc"--><!--webbot bot="AspInclude" endspan -->
<option VALUE="<%=FP_FieldHTML(fp_rs,"CampusID")%>">
<%=FP_FieldHTML(fp_rs,"Campus")%></option>

I need to add a new ddown menu with Month/Year where when i select a month and year I should be able to see all the records that month that year. Now my table doesnt have Month/Year column in it. Should I first add that column or.....?
