Default Search button doesn't search Access DB

Hello,

I have a Microsoft Access DB connected to a Windows Form Application.
This DB is going to be used as a tracking system. I tried to code the search button to check the Access file based on a certain criteria that is typed in by the user. There are several fields:
Last Name, First Name, etc. Below is the code I have to try to have search the Access DB file. Am I missing another piece that should return the data searched? I tried checking http://msdn.microsoft.com and I have a book for windows form applications but couldn't find an answer. Any help in the right direction would be appreciated.

  Public Sub ReadMyData(ByVal myConnString As String)
  Dim mySelectQuery As String = "SELECT Medical Record Number, Last Name, First Name FROM Table1 where lastname ='" + TextBox1.Text + "'"
        Dim myConnection As New OleDbConnection(myConnString)
        Dim myCommand As New OleDbCommand(mySelectQuery, myConnection)
        myConnection.Open()
        Dim myReader As OleDbDataReader
        myReader = myCommand.ExecuteReader()
        While myReader.Read()
            Console.WriteLine(myReader.GetInt32(0).ToString() + ", " _
            + myReader.GetString(1))
        End While

Thank you.

Default

Did you DEBUG???

Just for starters, did you put a breakpoint on the line where you create the query and make sure that the SQL was valid?

If it looks valid, did you then take that string and try it WITHIN ACCESS? See if that query actually returns anything?

p.s.: Just FYI, that query is *NOT* legal SQL. Which I guess means I know you didn't debug.

p.p.s.: Here's a hint for you: You are doing a SELECT for "Last Name" and yet your WHERE clause is trying to match up on the field "lastname". *SURELY* that table doesn't have BOTH a field named "Last Name" *and* one named "lastname". Surely.
