I have a page with 2 frames. In the top frame is a form called invoice.php. In it you type in an invoice number and then post it. I am wanting this post to be sent to 2 pages that will open in both the top and bottom frames. The top page is called invoicelab.php and the bottom is called invoice2.php. The information that I am posting is called workorder. The form page looks like this - --- Enter workorder number

What is the best way to pass this information onto both invoice2.php and invoicelab.php. Thanks
