--------------------------------- ORIGINAL TEXT ---------------------------
I've created a JavaScript toaster popup to show info about an individual row. It works great in FireFox...but it goes down in flames in IE.
...suggestions and help appreciated.
WHAT I THINK IS FAILING: I think I declared the "Toaster" class wrong and IE isn't doesn't recognize it as an array. As such, when I call "PopUp(clientId)" on the toaster it fails becuase it doesn't traverse the array.
Additionally, FireFox populates the array correctly in the documents "ready" function...but I'm not sure IE is doing so.
Lastly, since I am still new to JavaScript it (obviously) could be HOW I am creating the classes (as well).
WHERE IT FAILS: The code fails because the value of "target" is null. This variable is null because IE doesn't seem to traverse the Toaster (array).
this.PopUp = function(clientId) {
var target = null;
jQuery.each(this, function() {
// Hide previous
if (jQuery(this)[0].IsUp)
jQuery(this)[0].PopDown();
if (jQuery(this)[0].ClientId == clientId)
target = jQuery(this)[0];
});
// Show current
target.PopUp();
}
THE FULL CODE SET: Thanks for the help...

I need help on the following:
<ul>
<li>
This works GREAT in FireFox
</li>
<li>
IE doesn't seem to recognize the Toaster class as being an array.
</li>
</ul>
<div style="width: 300;">
<label style="display:block;color: #660000;">INDIVIDUAL pieces of toast work fine in IE:</label>
<input type="button" value="Down (row 3)" onclick="myToast.PopDown();" />
<input type="button" value="Up (row 3)" onclick="myToast.PopUp();" />
</div>
<br /><br />
<label style="color: #660000">Clicking a row IS SUPPOSED TO toggle a "piece of toast" for that row.</label>
