Triple Dropdown - A to B and B to C

I have a problem with a dynamic dropdown with three instances of dropdown menus on a page. Each dropdown is using a separate RecordSet. When dropdown_A is selected it populates the list in dropdown_B. When dropdown_B is selected from the newly populated list it populates dropdown_C.

I am receiving a javascript error "eventDay_WAJA is undefined" and eventDay is a Dynamic Array created from one of the recordsets to populate dates.

URL = index.cfm?category=rsvp and use the tab labeled 'Event Selections'
I have used the documentation in the help file to create the page. My final goal is to create three dropdown menus where the menu1 affects menu2 and menu2 affects menu3. So it would be a two (2) step process. First choose the events which populates the days available and then a day is chosen which gives a price.

There are 2 dynamic arrays: eventDay and eventPrice
There are 3 menu fields: Event, Day, and Price

I also am receiving a second error for Coldfusion where it states that a duplicate function cannot be executed more than once on function "WA_DD_Replace" so I have been deleting the duplicate instance in the code view.
