Sql Statement Problem in VB6

I am having trouble with a SQL Statement.

I can get it to work with fields that have numeric values, but when I set up the fields that I need that contain text values, I get the following error:

"No Value given for one or more required parameter"

I hope I am just overlooking something small and quick to fix...

If you need more info just ask...

Thanks

Here is my code:

**** Code that causes error ******
**** Code that I need to work with text data ******

Function MyGetTestPhase()

Dim cnn As adodb.Connection
Dim rst As adodb.Recordset
Set cnn = New adodb.Connection
Set rst = New adodb.Recordset
Dim cmd As New adodb.Command
Dim objrs As adodb.Recordset
Dim strsql As String

dbSrc = "h:\Access\NT\NT_Cat_dbs.mdb"

cnn.Open "PROVIDER=Microsoft.Jet.OLEDB.3.51;Data Source=" & dbSrc

Set cmd.ActiveConnection = cnn

rst.Open "[Test Animals]", cnn

*****Database Field that is Text*******
NTValue = "NT945"
***************************************

strsql = "Select [Test Animals].[Test Number] " & _
         "From [Test Animals], [Test Information] " & _
         "Where [Test Information].NT = " & NTValue

Set objrs = cnn.Execute(strsql)

test = objrs![Test Number]

End Function




*******  Code that works ****
*******  Code that contains Numeric data ******

Function MyGetTestPhase()

Dim cnn As adodb.Connection
Dim rst As adodb.Recordset
Set cnn = New adodb.Connection
Set rst = New adodb.Recordset
Dim cmd As New adodb.Command
Dim objrs As adodb.Recordset
Dim strsql As String

dbSrc = "h:\Access\NT\NT_Cat_dbs.mdb"

cnn.Open "PROVIDER=Microsoft.Jet.OLEDB.3.51;Data Source=" & dbSrc

Set cmd.ActiveConnection = cnn

rst.Open "[Test Animals]", cnn

*****Database field that is numeric******
PhaseValue = 10
*****************************************
strsq2 = "Select [Test Animals].[Test Number] " & _
         "From [Test Animals], [Test Information] " & _
         "Where [Test Information].Phases = " & PhaseValue

Set objrs = cnn.Execute(strsq2)

test2 = objrs![Test Number]

End Function

text fields require that the parameters be enclosed in single quotes, e.g.,

strsql = "Select [Test Animals].[Test Number] " & _
        "From [Test Animals], [Test Information] " & _
        "Where [Test Information].NT = '" & NTValue & "'"

use

strsql = "Select [Test Animals].[Test Number] " & _
        "From [Test Animals], [Test Information] " & _
        "Where [Test Information].NT = '" & NTValue & "'"
