Help with non-typical pop up

I’m using a 3rd party website for a business that has the option to popup a windows after an application submission.. so I do not have the ability to add anything more than a URL to set a location for the popup page. What I need is for the page I created to be sized to width=883,height=400. I’ve been trying the following script:

[I]<!– Begin
function popUp(URL) {
day = new Date();
id = day.getTime();
eval(“page” + id + ” = window.open(URL, ‘” + id + “‘, ‘toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=883,height=400,left = 248.5,top = 280’);”);
}
// End –>
</script>[/I]

This script works when i can link it from one of my own pages, but I cannot do that going through a 3rd party site for the popup. Can someone suggest a code that would allow the page to size and have a bollian value of o for toolbar, location, statusbar, menubar, resizeable, etc? I have tried a ‘replace’ value, but it doesn’t do what I want it to do. Please help.
