Crystal Reports asking for logon

I'm trying to get started with Crystal Reports using a reduced code approach. I tried inserting a SqlDataSource, CrystalReportViewer and CrystalReportSource as you can see below, with nothing inserted in the codebehind.
I do other consults to the same database with the connectionstring used here and defined at web.config so that's not the problem (i think). Shouldn't i be able to at least get past the login screen with that, and if not, what am i doing wrong at the moment?

Code:

---

<formid="form1"runat="server">
<div>
<asp:SqlDataSourceID="SqlDataSource1"runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString1 %>"
ProviderName="<%$ ConnectionStrings:ConnectionString1.ProviderName %>"
SelectCommand="SELECT * FROM [Report] WHERE ([CodeU] = ?)">
<SelectParameters>
<asp:QueryStringParameterName="CodeU"QueryStringField="codeQS"
Type="Int32"/>
</SelectParameters>
</asp:SqlDataSource>
<CR:CrystalReportSourceID="CrystalReportSource1"runat="server">
<ReportFileName="Print.rpt">
<DataSources>
<%--TableName="Report" --%>
<CR:DataSourceRefDataSourceID="SqlDataSource1"/>
</DataSources>
</Report>
</CR:CrystalReportSource>
<CR:CrystalReportViewerID="CrystalReportViewer1"runat="server"
AutoDataBind="True"GroupTreeImagesFolderUrl=""Height="1202px"
ReportSourceID="CrystalReportSource1"ToolbarImagesFolderUrl=""
ToolPanelWidth="200px"Width="1104px"/>
</div>
</form>
