Add a Parameter Value in SSRS

I have a report already setup on the ReportServer. And its subscription as well. What I'm trying to do is add the ParameterValue "CC" and some email addresses then send the email out. It doesn't seem to work.

My code:

Dim emailReader As SqlDataReader = selCount.ExecuteReader
Dim emailsTest As List(Of String) = New List(Of String)
emailsTest.Add("test1@pen.com")
emailsTest.Add("test2@pen.com")
emailsTest.Add("test3@pen.com")
emailsTest.Add("test4@pen.com")
If emailReader.HasRows() Then 'checks to see if there any quotes in query

    For Each subscrp As rs.Subscription In subscr
        Dim allV开发者_StackOverflow社区alues = subscrp.DeliverySettings.ParameterValues
        Dim allValuesList As List(Of ReportTriggerTemplate1.rs.ParameterValueOrFieldReference) = allValues.ToList()
        Dim CCParameter As ReportTriggerTemplate1.rs.ParameterValue = New ReportTriggerTemplate1.rs.ParameterValue()
        CCParameter.Name = "CC"
        CCParameter.Value = String.Empty
        allValuesList.Add(CCParameter)
        Dim toValue = CType(allValuesList.Item(7), ReportTriggerTemplate1.rs.ParameterValue)

        For Each testEmail As String In emailsTest
            Dim ownerEmail As String = testEmail
            If toValue.Value.Contains(ownerEmail) Then
                'skip
            ElseIf toValue.Value = String.Empty Then
                toValue.Value += ownerEmail
            Else
                toValue.Value += "; " & ownerEmail
            End If
        Next
        subscrp.DeliverySettings.ParameterValues = allValuesList.ToArray()
        Dim hello As String = "hi"
        tr.FireEvent(EventType, subscrp.SubscriptionID) 'forces subscription to be sent
    Next

What I'm adding to toValue.Value doesn't seem to be adding to the report's CC subscription field at all. So what am I missing?
