Problem With Insert Using SQLDataSource

I have a table with 2 columns - "memberid" is a guid and "Interest" is a string. In an aspx page I want to read in all values of "Interest" for a given "memberid" and display approprite checkboxes as checked. The user can then change which boxes are checked and I want to record the new list of selected items in the table. I created a SQLDataSource (see below) but when I run it, I get this error:

========== Error ===========

Disallowed implicit conversion from data type sql_variant to data type uniqueidentifier, table 'DB_136571.dbo.gs_MemberInterests', column 'memberid'. Use the CONVERT function to run this query.

============================

The only use of this SQLDataSource is to delete all entries for a given user and then insert an entry for each checked checkbox. The code to set the session variables is as follows:

======== Code ============

Dim guidMemberidAs Guid =CType(user.ProviderUserKey, Guid)

Session("currmember") = guidMemberid

....

Session("currinterest") =CType(item.FindControl("CheckBox1"), CheckBox).Text

==========================

Any ideas of what I am doing wrong here?

========= SQLDataSource ==========

<asp:SqlDataSourceID="SqlDataSource2"runat="server"ConnectionString="<%$ ConnectionStrings:GoodSamSiteDB %>"

DeleteCommand="DELETE FROM [gs_MemberInterests] WHERE [memberid] = @.memberid"

InsertCommand="INSERT INTO [gs_MemberInterests] ([memberid], [Interest]) VALUES (@.memberid, @.Interest)"

SelectCommand="SELECT memberid, Interest FROM gs_MemberInterests WHERE (memberid = @.memberid) AND (Interest = @.interest)">

<DeleteParameters>

<asp:ParameterName="memberid"Type="Object"/>

</DeleteParameters>

<SelectParameters>

<asp:SessionParameterName="memberid"SessionField="currmember"Type="Object"/>

<asp:SessionParameterName="interest"SessionField="currinterest"/>

</SelectParameters>

<InsertParameters>

<asp:ParameterName="memberid"Type="Object"/>

<asp:ParameterName="Interest"Type="String"/>

</InsertParameters>

</asp:SqlDataSource>

Type="Object"

Thanks. I assume you are referring to the fact that the "Type='Object'" has to be removed. I just found a reference to that bug. That cleared the problem.
