Hi Royce,\

Try this:

```
var qry = (from test in  je.employee                  where test.emp_email.Equals(TxtUserName.Text) & test.emp_pass.Equals(TxtPassword.Text)                   select test).FirstOrDefault();   var qry2 = (from test1 in je.employer                    where test1.c_mail.Equals(TxtUserName.Text) & test1.c_pass.Equals(TxtPassword.Text)                    select test1).FirstOrDefault();    if (null!=qry)    {        Response.Redirect("EmployeeHome.aspx");    }    else if(null != qry2)    {         Response.Redirect("EmployerHome.aspx");             }    else    {        Label1.Text = "Incorrect username or password!";    }
```
