List Box Search

I have a table and form called patient info

I created a list box from the patient info with the following

Last Name
First Name
Social Security
Date of birth
Account Number

I created a text box above the list box to search records
but dont know how to link the two

Also created Option buttons

Last Name
First Name
Social Security
Date of Birth
Account #

So if i need to search by last name i click on the last name option box and type the last in the search text above the list box and so forth any ideas.
