Type mismatch?

I am using the following ASP code to test a DLL I wrote in C#:



<%
Set fc = Server.CreateObject("BuyersFund.FaxCOM.FaxCOM")
Dim useSQL
useSQL=""
fc.LetterID = "LDL"
fc.TemplatePath = "C:\\NEOTemplates\\LenderDeals_New_English.dot"
fc.SendMethod = "Create"
fc.LanguageID = 20
fc.LenderSpecialMessage = "default message"
fc.MonthValue = 2
fc.YearValue = 2004
Response.Write(fc.YearValue)
fc.LetterEntryID = 70000

useSQL = "SELECT entryLenderView.loname as LO, "
useSQL = useSQL & "entryLenderView.workNumber as LenderPhone, "
useSQL = useSQL & "liv.PhoneInfo, "
useSQL = useSQL & "entryLenderView.company as LenderInfoName, "
useSQL = useSQL & "liv.AddressInfo, "
useSQL = useSQL & "liv.CityInfo, "
useSQL = useSQL & "liv.StateInfo, "
useSQL = useSQL & "liv.ZipInfo "
useSQL = useSQL & "FROM entryLenderView "
useSQL = useSQL & "INNER JOIN (select * from lenderInfoCompleteView) liv "
useSQL = useSQL & "ON entryLenderView.workNumber = liv.PhoneInfo "
useSQL = useSQL & "WHERE (entryLenderView.Status <> 'Cancelled') "
useSQL = useSQL & "AND entryLenderView.entryID = 70000"
useSQL = useSQL & " AND entryLenderView.loName <> '' "
useSQL = useSQL & "AND (datepart(mm,IsNull([Funded],0))=2) "
useSQL = useSQL & "AND (datepart(yy,IsNull([Funded],0))=2004) "
useSQL = useSQL & "GROUP BY entryLenderView.loname, "
useSQL = useSQL & "entryLenderView.workNumber, "
useSQL = useSQL & "liv.PhoneInfo, "
useSQL = useSQL & "entryLenderView.company, "
useSQL = useSQL & "liv.AddressInfo, "
useSQL = useSQL & "liv.CityInfo, "
useSQL = useSQL & "liv.StateInfo, "
useSQL = useSQL & "liv.ZipInfo "
useSQL = useSQL & "HAVING entryLenderView.workNumber Is Not Null "
useSQL = useSQL & "ORDER BY liv.ZipInfo, "
useSQL = useSQL & "entryLenderView.loname"


fc.SQLStatement = useSQL
fc.GenerateRequest()

Response.Write("Done Testing BF Fax Communications Client")
Set COMObj = Nothing
%>




The problem is with this line:


fc.LetterEntryID = 70000


Which corresponds to the following SETTER  / GETTER property in my C# code:


      public long LetterEntryID
            {
                  set
                  {
                        FAXCOM_ENTRYID = value;
                  }

                  get
                  {
                        return FAXCOM_ENTRYID;
                  }
            }


I am getting the following error:



HTTP 500.100 - Internal Server Error - ASP error
Internet Information Services

How can it be a type mismatch?????????????????????
