ExcelBanter - Problem Using If/Then Statements To Hide Columns

Hi all,

I've been working on a print macro that allows the user to enter a
start date and an end date, and thereby automatically hide the
irrelevant columns on each worksheet when the sheet prints.

When the user selects a date from the two drop down menus, this puts a
number into ListBox3 and ListBox4 depending on their selection. The
macro then hides the columns before the start date and after the end
date, before printing the selected sheets and then reverting the
sheets to their former, unhidden state.

It's so close to working. It doesn't generate any errors when the
code runs, and it either hides the columns before the start date OR it
hides the columns after the end date. Unfortunately, it never manages
to do of these things both at once!

My testing has indicated that the problem occurs because the script is
alternately failing to recognise the value of ListBox3 ('D') or the
value of ListBox4 ('F') - see code below. Why it should only
recognise one at a time, and not even the same one for that matter, is
beyond me.

If anyone can make any suggestions towards resolving this, your wisdom
would be greatly appreciated!
