Okay.

Here is my problem.  I am trying to create a popup that displays on a
submit.
---
<script LANGUAGE="javascript">

function db_update_popup(){
if (mywin) mywin.focus();
else
var mywin = window.open("/database_update.htm","popupwindow","top=0,
left=150,
toolbar=1,location=1,directories=0,status=1,menubar=0,resizable=1,scrollbars
=0,width=300,height=250");
}

</script>

 <input type="submit" src="/images/buttons/remove.gif" width="79"
height="18" border="0" name="DELETE" value="Remove"
onClick="db_update_popup()" onClick="return VerifyAction('You are about to
delete an announcemment!');" />

----
This brings the popup to front if the window is already open, or create a
popup if one isn't open.  This seems to work fine.
=============================

Then within the popup I am trying to set a cookie to determine if the user
no longer wants the popup to be displayed on every submit.

So I check for a cookie on focus or on load and then either pop the window
up on a delay or blur the window so that it stays in the background. If the
user selects the "don't show popups" button, I am trying to create a cookie
and blur the popup.  This unfortunately isn't working and  I am sure there
is a simpler way to do all of this.
---
<script language="javascript" type="text/javascript">
<!-- Hides code
  expireDate=new Date
  expireDate.setYear(expireDate.getDay()+1)

function createcookie () {
 if (document.cookie == "") {
  userName = "blank"
  document.cookie = "userName="+userName+";expires="+
expireDate.toGMTString()
  document.write("cookie created")
 }
}

function checkcookie () {
 if (document.cookie.split("=")[1] == "NoMorePopups") {
  document.write(document.cookie.split("=")[1])
  window.blur()
 }
else {
  setTimeout('self.focus()', 1000);
 }
}

function setCookie() {
 userName = document.myForm.nameField.value
 document.cookie = "userName="+userName+";expires="+
expireDate.toGMTString()
 window.blur()
}

// stop hiding-->
</script>
</head>
<body onfocus=checkcookie()>
<span onload=createcookie() />

<form name=myForm>
<input type="button" value="NoMorePopups" name="nameField"
onClick="setCookie()">
</form>
---

Any and all ideas / feedback would be greatly appreciated.
