The way that I have done this is have the items that are to be loaded into
the first combo box in the rows of the first column of a table is another
Word document and the items for the second combo box as paragraphs in the
cells of column 2 with the data in each cell in column 2 adjacent to the
item in the cell in column 1 to which it is adjacent.
If you need more help, post back and I can dig out some code.
Hope this helps.
Please reply to the newsgroup unless you wish to avail yourself of my
services on a paid consulting basis.
