I'm building a pro-forma financial statement that will evaluate an
investment for a given number of years. I need to be able to put in a
number specifying how long I will hold the investment in cell I-6 on a
worksheet called "Data Entry", and then add or subtract columns on a
worksheet called "operating Statement" based on the number from the
data entry worksheet.

The maximum holding period is 10 years, so I figure the easiest way to
do this is to just build my worksheet to have columns for years 0-10,
and then use the macro to hide columns if the holding period is less
than 10. Example, if the holding period is 5, I want the macro to hide
columns 6-10.

How do I do this?

Thanks.
