Chart with parameters in SSRS 2012

Question

Hello,
  I want to do a chart (line chart particularly, but I will take an answer for any chart as they all probably work similarly) with one parameter passed (hospitalid) and two values returned (BedDays and MonthYear).  MonthYear is how the horizontal
line is divided, by each month, and the BedDays should be the number of patient stays in beds in that month.  Doesn't matter if it's sum of bed days or bed days, because a sum is made in the stored procedure, and MonthYear is unique.
  I have spend a few days on this problem, working a lot on it, and I keep running into errors, trying various methods.  I don't know where all my errors could be coming from, it could be in the aspx, it could be in the report design, or it could
be in the code behind, so I am hoping someone can give me a step by step solution to this problem which should be simple, but apparently is not because there is no worthwhile help that I can find on the internet.  It should work for SSRS 2012, I do not
have a choice of using an earlier version for this project.  Please include everything I need to do in the report GUI, in the aspx file, and in the code behind, as any little error in any of these could keep this from working and make it very difficult
for me to pinpoint what is going wrong.
  Please help!

I'm using Visual Studio 2013.  According to what I read, there is no report preview in newer versions?
I created a report and then added a line chart.
I used my connection and under Data Set Name I put: AllevantReportDataSetB
Under Choose the Dataset, I selected AllevantReportDataSetB as the data source. 
For "Name" I chose DataSetB
The stored procedure works (that is all you need to know, because the inner detail shouldn't make a difference), and when a parameter @facilityid is passed to it, it returns a table with the first column named MonthYear which is a date of all of the months,
years, and the first of each month from the beginning to end of the data - and the second column is BedDays, the number of total stays in a bed for all of the patients at the facility.
In Category groups, I have MonthYear, and in Values I have BedDays (actually [Sum(BedDays)], but the sum shouldn't matter, because the MonthYears are unique so there is only one MonthYear, there is not more than one of the same month in the whole data set)
My .aspx is the following:
<rsweb:ReportViewer ID="ReportViewer1"
runat="server"
ProcessingMode="Remote"
Font-Names="Verdana"
Font-Size="8pt"
InteractiveDeviceInfos="(Collection)"
WaitMessageFont-Names="Verdana"
WaitMessageFont-Size="14pt"
Width="95%"
Height="99%" ShowDocumentMapButton="False"
ShowPromptAreaButton="False" Visible="true">
<LocalReport ReportEmbeddedResource="MySolution.Report5.rdlc">
<DataSources>
<rsweb:ReportDataSource DataSourceId="Report1DataSource" Name="DataSetB" />
</DataSources>
</LocalReport>
</rsweb:ReportViewer>
And my VB code behind is the following:
Protected Function GetReportDataTable() As DataTable
Dim Conn As New SqlConnection(ConfigurationManager.ConnectionStrings("sql").ToString)
Dim Command As New SqlCommand("BedDays", Conn)
Dim BedDaysDataTable As New DataTable()
BedDaysDataTable.Columns.Add("MonthYear", GetType(DateTime))
BedDaysDataTable.Columns.Add("BedDays", GetType(Int32))
Command.CommandType = CommandType.StoredProcedure
Command.Parameters.Add("@facID", SqlDbType.Int).Value = 20
Command.Connection = Conn
Conn.Open()
Dim DataReader As SqlDataReader = Command.ExecuteReader()
BedDaysDataTable.Load(DataReader)
Conn.Close()
Return BedDaysDataTable
End Function
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
FillMetricsDDL()
FillFacilityDDL()
Dim rds As ReportDataSource
rds = New ReportDataSource("Report1DataSource", GetReportDataTable)
Dim ReportParameters As New List(Of ReportParameter)
ReportParameters.Add(New ReportParameter("@facID", 20))
ReportViewer1.LocalReport.DataSources.Add(rds)
ReportViewer1.LocalReport.ReportPath = "Report5.rdlc"
ReportViewer1.LocalReport.Refresh()
End If
Common.Chosen(Me)
End Sub
  I am getting the error where the report should be
Unable to connect to the remote server, no connection could be made because the target machine actively refused it.                                        
But I suppose once this error is resolved, there will be more, because I really do not quite know exactly how SSRS charts with parameters in SSRS 2012 are suppossed to work, in code behind, in aspx, and in the charting, and how it all ties together.  So
some complete guidance to show ALL the places where I am going wrong here would be much appreciated, not just an attempt to solve the one error I have above, which may not be the sum total of all of my problems here.
Unless, of course, it IS the only error which would be GREAT.
