QUERY WILL NOT WORK DIFFERENT ERROR EACH TIME

I can't get this sql query to load the datagridview.First off I have a table called nflplayerspass it has the most important field called Season with this I can filter a season Now look
In SQLEXPRESS MANAGEMENT Studio I can write queries no problem However when I load my query I get ambitious column Season so If I takeaway season from the query and combobox I can retrieve data. I am angry and frustrated How can Season be in database but in my winform I can't pull any data based on year Without Season(year) I'm dead in the water Here is queryMaybe I missed something.  
Here is the code

 Public Sub GetpassingNfl()

        Dim ds As New DataSet

        Dim SelectCommand As New SqlCommand

        connetionString = "Data Source=tsnappdev01;Initial Catalog=TSN2;User ID=sa;Password=sportsrus"
        connection = New SqlConnection(connetionString)

        sql = " Select PK_NFLPLAYERSPASS,np.FirstName,np.LastName, t.Fullname,np.PlayerID,np.TeamID, npp.SeasonType,npp.Season,npp.Conference,npp.Att,npp.Comp,npp.Yards,npp.Long,npp.TD,npp.Inter,npp.Sacks,npp.SKYds,npp.Rating FROM NFLPlayersPass npp "
        sql += " join NflPlayers np on np.PlayerID = npp.PlayerID join Teams t on t.TeamID = npp.team WHERE"
        sql += " npp.Season = " & cmbseason.SelectedText & "Order By np.Lastname"

       
        If cmbseason.Text = "" Then
            Exit Sub
        End If
        

        connection = New SqlConnection(connetionString)

        Try

            connection.Open()
            adapter = New SqlDataAdapter(sql, connection)
            adapter.Fill(ds)
            connection.Close()
            dvgPass.DataSource = ds.Tables(0)

        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try

        dvgPass.ColumnHeadersHeight = 55
