ASP SQL Query string syntax issue.

Can someone please help me to understand why I am getting this error:

Microsoft OLE DB Provider for ODBC Drivers error '80040e14'

[Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid column name 'Lab@xyz.org'.

/trainingSessions/SQLRuns2.asp, line 58


 strSQL3 = "UPDATE _Employees SET Pager = e.LName + ""Lab@xyz.org"" FROM _Employees e INNER JOIN _Department d ON e.reportsto = d.DeptHead WHERE e.isactive = 1 AND e.isScientific= 1 AND e.reportsto = " & Session("strPIID")                                        
 set rsEMP = oConn.Execute(strSQL3)


This is the result in SQL Server Profiler:

UPDATE _Employees SET Pager = e.LName +  "Lab@xyz.org" FROM _Employees e INNER JOIN _Department d ON e.reportsto = d.DeptHead WHERE e.isactive = 1 AND e.isScientific= 1 AND e.reportsto = 7165
