Populate text boxes from query results

I have an Access DB with several tables.  I have a query:

"SELECT Techs.LName, Techs.FName, Techs.Email_Address
FROM Techs
WHERE (((Techs.LName)=[Forms]![Records]![txtLName]));"

What I need to do is:
1) run the query from code on the lost focus event of the txtLName.text
2) if more than one name (e.g I have 3 techs named smith) I need a popup that allows the user to select which "smith" they want to work
3) populate the txtFName.text box with the techs first name
4) populate the txtEmail.text box with the techs email address

I tried this: sSql = ("SELECT Techs.LName, Techs.FName, Techs.Email_Address FROM Techs WHERE Techs.LName= '" & [Forms]![Records]![txtLName] & "'")
this query works with access, but I would like to do this from code


since the form I am using is in access do I need to create a connection string?
I know I need a recordset to loop through the DB.

Man I think I bit off more than I can chew! Some day I will remember what NAVY actually means (Never Again Volunteer Yourself).
