So here's what I'm starting with and what I'd like to do with it.

I start with a large spreadsheet with values in several columns. I
have a macro that goes through and cuts out columns by specfic column
values (A, G, L thru Q, etc.). But, since the reporting department
responsible for maintaining this file doesn't do such a great job of
maintenance, this specific cut/paste by column isn't working any
longer.

What I'd like to do is have a window pop up with two fields. On the
left is a list of all the Headers found in Row 1. You can then select
which Headers you'd like to move over into the right hand side. When
the 'OK' button is pressed, the macro is executed and the un-selected
columns on the left hand side are cleared while the selected columns
are all re-organized and placed side by side with no blank columns in
between them. Can somebody please help me out on this?
