I have 10 rows in groupings of 2 (total of 5 groupings) that are
hidden. Based on user input in a cell I want to unhide the rows.

The user will input a number from 1 to 5 in cell A15. Each number is
to unhide 2 rows progressively. (Currently 20/21, 22/23, 24/25, 26/27,
28/29)

Example:
User input of 1 will unhide 20 and 21. An input of 2 will unhide 20,
21, 22, and 23. An input of 3 will unhide 6 rows. Etc.

Can VB do this? (If so where can I find the code or can you write it
here.)

Can it be automatic anytime that cell is changed or will I need to
create a button to run the specified macro code. (The automatic is
better but will take what I can get.)

Any help you can offer would be apprecaited.
