Default alert

Hi,

I am trying to write a function that returns an error message. If the user doesn't enter a valid email then an alert pops up, if the user doesn't enter a phone number then a different alert must appear. The problem is that if the user doesn't enter an email and a number then i don't want to alerts to appear. I want the error messages to appear in one alert. I tried writing the following function but it gives me the error: 'object is empty' and i think it is referring to the line alert(sat)


     function ValidateForm ()
{
var sat;
    if (document.Form1.txtEmail.value.indexOf("@")==-1)
    {
sat+="Incorrect email"
    return false;
    }


    if (document.Form1.txtMsg.value=="")
    {
sat+="Enter message"
    return false;
    }
  alert(sat)
    else
        {
    document.Form1.action="card.asp";
        }
        document.Form1.submit()
    }
*/

        </script>
