Dataset not defined when creating Crystal Report

I have a form (VB.NET) that connects to an Access database, and everything works just fine. But when I add a Crystal Report using "Add New Item" (even just a blank form), an error occurs in my form "Type drpReview.DsReview not defined" in the following line:

#Region " Windows Form Designer generated code "
Friend WithEvents DsReview As drpReview.DsReview

Why does adding a Crystal Report item cause my dataset to become "undefined"? What type of definition is it looking for?
