muliple forms and objects

Question

Hello, I have a solution with multiple forms under the same namespace. I want to be able to read the contents of a listbox on one form into a listbox on a second form. I can't seem to get them to work correctly. If I set one of the listbox to be public static, it works, but I then can't open the form in the form designer - it tells me that the listbox name is undefined. Can anybody help me with this problem? Thanks
