Input string was not in a correct format.

Hi,

I am trying to make a C/ODBC connection with a Navision Database through ASP.NET. This works good, but when i try to get other values other than CODE or TEXT, i get the error shown in the subject.

VB Code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       Dim dsn As String
        Dim sql As String
        Dim cn As OdbcConnection
        Dim cmd As OdbcCommand
        Dim dr As OdbcDataReader
 
        dsn = "DRIVER={C/ODBC 32 bit};"
        dsn = dsn & "DSN=DSNNAME;"
        dsn = dsn & "UID=user;"
        dsn = dsn & "PWD=pwd;"
        dsn = dsn & "sName=SRVRNAME;"
        dsn = dsn & "NType=tcp;"
        dsn = dsn & "CN=My Company;"
        dsn = dsn & "CSF=Yes;"
        dsn = dsn & "SERVER=N"
 
 
        cn = New OdbcConnection(dsn)
        cn.Open()
 
        sql = "SELECT No_, Name, Address, City, ""Phone No_"", Amount FROM "
        Select Case Request.QueryString("Table")
            Case 90000
                sql = sql & "Cust50"
            Case 90001
                sql = sql & "Cust500"
            Case 90002
                sql = sql & "Cust500"
            Case 90003
                sql = sql & "CustFull"
        End Select
 
        cmd = New OdbcCommand(sql, cn)
 
        dr = cmd.ExecuteReader(CommandBehavior.SingleResult)
 
        dtgCustomers.DataSource = dr
        dtgCustomers.DataBind()
        lblElapsed.Text = "Time needed to load: " & Environment.TickCount - Request.QueryString("ms") & " Milliseconds"
 
        cn.Close()
End sub

Does anyone know how i can solve this or at least make it be shown or parsed to string(the values do not have to be edited).
It is the Amount field that has the type Decimal.

Hope anyone can help me.

[EDIT:] Forgot to say i get the error when i connect it to the datagrid:
