SQLDataSource, Server Tag Not Well Formed

My query works correctly inside of query analyzer, but in my .aspx page I get the following error message, "The server tag is not well formed."
If I remove the parameters then the sqldatasource does not yield errors.  The parameters are passed from two textboxes on the page.

 Thank You.

My sqldatasource is:


<asp:SqlDataSource ID="sqlException"

runat="server" ConnectionString="<%$ ConnectionStrings:AttendanceConnectionString %>"

SelectCommand="SELECT ATTTblAttendance.UserID, ATTTblAttendance.Today, "

"ATTTblAttendance.AMBreakIn, ATTTblAttendance.LunchOut, "

"ATTTblAttendance.PMBreakOut, ATTTblAttendance.PMBreakIn, ATTTblAttendance.Logout, "

"ATTTblAttendance.Login, "

"ATTTblAttendance.LunchIn FROM ATTTblAttendance INNER JOIN "

"ATTWASDEmployees ON ATTTblAttendance.UserID = ATTWASDEmployees.EmployeeID "

"WHERE ((ATTTblAttendance.AMBreakOut IS NULL) OR "

"(ATTTblAttendance.AMBreakIn IS NULL) OR "
