How do I use iImportSession.GetTableEntryValue?

Like this?  It seems to return nothing

Dim sReturn As String = ""
MsgBox(oField.RecordType.ToString & " - " & oField.ValueType)
Dim oCCodeTableServer As New Blackbaud.PIA.RE7.BBREAPI.CCodeTablesServerClass
oCCodeTableServer.Init(Import.SessionContext)
Dim sValue As String = ""
sReturn = Import.GetTableEntryValue(sValue, Blackbaud.PIA.RE7.BBREAPI.ECodeTableNumbers.tbnumPhoneTypes, oCCodeTableServer, False, False, oField.ValueType)
MsgBox(sReturn & " - " & sValue)
Return sReturn

Answered my own question!

Easier way to look up the value table of field:

Dim oCCodeTableServer As New Blackbaud.PIA.RE7.BBREAPI.CCodeTablesServerClass
oCCodeTableServer.Init(Import.SessionContext)
sReturn = oCCodeTableServer.GetTableEntryDescription(oField.ValueType, Blackbaud.PIA.RE7.BBREAPI.ECodeTableNumbers.tbnumPhoneTypes)
