Using Javascript to search a share point list

[sweetsdecline]

I found this code a while ago that creates a drop down search box that will search a sharepoint list. I am extremely new to this so I am clueless in how I can modify this code to suit my needs. The code redirects to the same page with querystring data added to the URL. I was able to modify the drop down list and I changed the Column names to match the columns in my list. I changed to column names because it wasnt returning any records and I believe it is because it is referencing the columns that dont match my list. Once I did that it didnt work, It wouldnt return any records. I have a feeling it is because of this piece of code:

Search Field:
Person Name
Status
Case #
Date taken
DOB
other #
Notes
employee

Search text:
