Sort Data on Multiple sheets by single cell Entry

Hi All,

If possible does anyone have code to do the following.

On selecting a month using an in cell drop down list on Sheet1, the code will sort the data in all sheets in the workbook to show this selection.
Only Sheet1 and Sheet2 "hidden template" should not be sorted.

The selection would be January to december and allow for an all dates selection.
The dates are listed from sheets3 onwards in Column A, Row 2 and are shown as i.e. 12/06/08.

Any help will be fantastic.

Thanks
