Launching Javascript window from attached movie?

I’ve been attempting to launch a window from an attached movie, I’ve got the function to work but after it launches, the main window (with the flash file) relocates automatically with the message “[object Window]”

I’m presently using the following coding with the button’s AS:

getURL("\'\',\'Nubeau Guarantee\', \'toolbar=no, location=no, status=no, menubar=no, scrollbars=no, resizable=no, width=500, height=800\')");

I’ve attempted to setup a javascript function in the HTML and have the “getURL” call the function, but that doesn’t seem to work. Any help? Thanks
