OK, a newbie at UserForms in Excel. I want to make 2 combo boxes in Excel.
One has a named range which uses the data from the worksheet, which I
figured out, but when an item is chosen in the first combo, I want it to
requery and have a new list of items. What do I do to make this happen.

If Column 1 has Value1, Value2 in the data, then the 1st combo fills with
Value1 and Value2. Also, Column1 in the worksheet looks like this:
Column1
Value1
Value2

Then I have in Columns 2 and 3 the following, which I think I have to do to
represent what data to use for the 2nd combo.
Column2 Column3
Value1 A
Value1 B
Value1 C
Value2 AA
Value2 BB
Value2 CC

So how do I choose Value1 in the first combo (which reads from Column1), and
then have it show A,B,C in the 2nd combo?
