'writeDropDowns
'purpose - write three drop down boxes where the days available are based on month and year
'notes - this submits to the page each time a month or year is selected and recalculates the number
'           of days 
'       -I use a javascript function to submit my form, this may seem a bit much
'           but it allows me to customize better, If i want I can throw other validation in it, or
'           a frame target
