/*-----------------------------------------------------------------------------------------
-	12/07/2005  Brad Sulewski       Updating to work with city subfolders
-   12/19/2005  Brad Sulewski       WFM 2826 Updated CheckDate() to populate new hidden fields fromdatehidden and todatehidden for making the calendar popup default to current selected dates
-   12/22/2005  Brad Sulewski       Removed updating of hidden fields fromdatehidden and todatehidden and am calling Format10DigitDate directly in the call to the calendar popup in find_hotel_include.asp
-   12/29/2005  Brad Sulewski       Fixed CheckDate() -- when start date is < today, display the alert and update FromDate to tomorrow date to break the loop
-   01/18/2006  Brad Sulewski       Added function setCityAddress() to update the hidden City filed from the Search By Address Fields
-                                   Added function clearLatLong() to clear the lat and lon hidden fields when searching by address
-                                   Modified UpdateLatLong() to clear the Search By Address fields so that they do not interfear with the search if a location is selected after entering in an address
-   01/19/2006  Brad Sulewski       Modified setCityAddress() to clear the Town and State fields when entering an address to search by
-                                   And modified setCity() to clear the search by address fields when a new city/state is entered
-   01/26/2005  Brad Sulewski       Replaced with file from roomrate
-   01/31/2006  Brad Sulewski       Added clearAddress and clearChain functions
