Need help with multiple popups in a flash MX document

[batmmannn]

Can anyone provide the code to allow one popup window not to need to be closed before thw next pop up can come up? I found some code and someone that had code for it but when I use it I get errors and it does not work.
Here is the code I put in any help would be greatly appreciated

on (release) {
getURL("JavaScript:popup('BBpageflatB4.html');");
}

function popup(destination) {
window.open(destination,'BBpageflatB4.html', 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, width=475, height=625, left=50, top=50');
}

I get this error

**Error** Symbol=ch_pages, layer=button, frame=30:Line 6: Statement must appear within on handler
function popup(destination) {
