How to link imported data to form?

How to link imported data to form?

Hi,
 
     I would like to make a search form based on some data imported from excel.
 
(1) I have imported the excel data via the excel migration tool but I cannot find the data anywhere (although there was a message to say that data has been uploaded successfully)
 
(2) How do I link this data to my search form? I can't use the lookup form field right?
 
Example of the search form:
 
Year :       (to be able to select year from dropdown)
Class: 1A, 1B, 1C (etc corresponding to the year)
Name of Pupil : XXX (corresponding to the year and class they are in)
 
So if I want to find a student from a particular class in 2010, I would first need to select 2010 from "Year", followed by their "Class" and then a whole list of pupils' names will appear.
 
Any idea how to do this? I'm an idiot when it comes to scripting as well... Help needed!!!!!!
 
Thanks in advance!!!!!
