Automated Worksheet Creation from Cell Data

Is there a way to write a macro that will create new worksheets based on data in a particular cell? Here is my issue specifically: On a "master" worksheet, I have a drop-down menu within a cell that allows the user to select a number from 1-20. After selecting the number 6 (for example), I would like 6 new worksheets to be created, identical to another, separate worksheet. I can try to get more specific, but does anyone have any ideas on how to go about this with the information provided? Disclaimer: I'm new to macros. Thanks to whoever can help.

When I run this macro it just jumps to the sheet that needs to be copied but doesn't create new sheets based off the number selected in the drop-down. After using the drop-down to select a given number, I went to macros and selected run. Should I be doing something else? Thanks for the quick response.

Still nothing. I'm probably doing something wrong so here is my file specifically: There are two worksheets, one named "Master" and one named "Box 1." Within cell D16 on the "Master" worksheet is a drop-down box. Ideally, if I select a given number from the drop-down menu on the "Master" sheet, I would like an equal number of new worksheets created based on (copying) the "Box 1" sheet. If possible, I am also looking for these new worksheets to be named incrementally, such as Box 2, Box 3, Box 4, etc. This last part is not necessarily needed, just an added question.

Also, I've been pasting the supplied code into Visual Basics, saving, then going to the drop-down menu and selecting a number, then running the macro. Is this process incorrect? This could be part of the problem. Thanks again.
