custom validator - problem returning bit/boolean in DAL

I have a custom validator which does some server side validation:

 Protected Sub cvDuplicateName_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles cvDuplicateName.ServerValidate

Dim strLegalNameNew As Object = Me.txtLegalNameNew.Text
Dim qta As New QueriesTableAdapter Dim objResult As Object = qta.udf_ExistsDuplicateCompanyName(strLegalNameNew)
'Dim bool As Boolean = qta.udf_ExistsDuplicateCompanyName(strLegalNameNew)   THIS DOESN:T WORK
'Dim int As Integer = qta.udf_ExistsDuplicateCompanyName(strLegalNameNew)   'THIS DOESN"T WORK EITHER - what gives?

If objResult = True Then
   args.IsValid = "false"
Else
    args.IsValid = "true"
End If


End Sub

 The problem is no matter what I do, objResult always is returning false and I can't fig ...
