I have this bit of code to make sure an email address is entered

if (theForm.frmEmail.value == "")
  {
    alert("Please enter a value for the \"Email Address\" field.");
    theForm.frmEmail.focus();
    return (false);
  }

It only checks to make sure something is entered. You can just enter 1 character and it accepts it as an email address. How can I change this bit of code so that it at least checks there is an "@" entered?

Here ya go:
