Find Button in Data Access Page

I created a form in Access 2003. I've saved the form as a Data Access Page (HTML). Everything except the Search (find record) button works.

I can use the navigation bar to jump to the first or last record, but how do I jump to a specific record without a search feature?

I found an article on MSDN titled "Adding Custom Filtering and SEARCH FUNCTIONALITY to a PAGE". This appeared to be the solution I was looking for, but after implementing it I get script errors when I open the Data Access Page. The script is expecting a "Then".

HELP!
