[RESOLVED] (VS2010) Multi-Field Mathematical SQL Query

While I do know how to create a mathematical SQL query I am having difficulties with creating a statement involving multiple rows, each row chose by one or more attributes selected in the GUI of my program. To get a better idea of my purpose:

I have a page with 4 different part types. Each part type has multiple selectable values that are chosen by the user. When all values of each part type are chosen a total is calculated (this is the total between all 4 part types). All prices are in the same data table.

I have an idea of how this must be done (Looped SQL query) but I have never dealt with this before and would appreciate a nudge in the right direction.

Thanks for any leads you may offer. :)

Here is what I have for the function so far:

Code:

---

Public Function GetPrice(ByVal Part_Number As String) As Double
        Try
            Using udtConn As New SqlConnection(sBoMConnectionString)

                Dim daPrice As New SqlDataAdapter(New SqlCommand("SELECT Last_Quote_Amt FROM Part Where Part_Nbr = '" & Part_Number & "'", udtConn))
                Dim dsPrice As New DataSet

                dsPrice.Tables.Add("Part")
                daPrice.Fill(dsPrice.Tables("Part"))

                Me.BoMDataSetBindingSource.DataSource = dsPrice.Tables("Part")
                daPrice.Fill(dsPrice)

                Return dsPrice.Tables("Part").Rows(0).Item("Last_Quote_Amt")

            End Using
        Catch ex As Exception
            'An error occured while pulling data
        End Try
    End Function
