Kevin,
I made it work by using the following code:

Dim rptWarranty1 As New CrystalDecisions.CrystalReports.Engine.ReportDocument
rptWarranty1.Load(Server.MapPath("rptWarrantyRegistrationReport.rpt"))
rptWarranty1.SetDataSource(WarrantyDS1)
crvWarranty1.ReportSource = rptWarranty1

What I was originally trying to do is something like I would do in a windows form:

Dim rtpWarranty1 As New rptWarrantyRegistrationReport

And that was the code samples I have been finding, but when I tried doing that, Intellisense would not list rptWarrantyRegistrationReport.

(and I just noticed that I did one of my biggest pet peeves by using redundant naming. I always get worked up when I see somebody names a table something like tblCustomerTable, but I did the same thing with my report.)
