Hi,



I would really appreciate some help with the following:



1. I would like to create a user form that has two list boxes.

2. The first list box should provide a listing of all open excel workbooks.

3. The second list box should display the sheets of the workbook that

is selected in the first list box.

4. The code should prevent duplicate workbooks or worksheets from

being displayed in the list boxes.



I am working with Windows XP and Excel 2002.



Any advice on how to accomplished the above would be greatly appreciated.



Thanks,



Steve
