Check box opens new window and checks a new box

[Curtis Lokszyn]

I was wondering if there was any way to do this:

I have a site that has a catalog. There are 10 - 20 items per page and about 15 pages/categories. Each item will have a check box. When a checkbox is clicked a window will open (containing a list of EVERY item, quantities, etc.) and a check box next to that particular item will be automatically checked.

Then as the user clicks through the catalog and checks off boxes they will be filled in in the new window as well.

Basically I need to know how to check a box in one window and have it check a box in another window at the same time.

Thanks.

If the secondary window is opened with window.open(), the parent window will receive a reference to the child window, and the child window can access the parent through the opener reference.
