Depending on your data layout it might be more efficient to store all data in one sheet then use a PivotTable to group by Months & Years

This might helpyou get started

Post back if you need further help, some dummy data in a workbook would be useful

Private Sub CommandButton1_Click()

'Unhides and take you to the January 09 sheet'
'you can add more months to be unhidden here'

  Sheets("January 09").Visible = True
   Sheets("February 09").Visible = True
    Sheets("March 09").Visible = True

   Application.Goto Reference:=Sheets("January 09").Range("A1"), Scroll:=True
   
'Hides all of the months not associated with this year'
'you can add more months to be hidden here'

     Sheets("January 10").Visible = False
    Sheets("Februray 10").Visible = False
   Sheets("March 10").Visible = False


End Sub

i was thinking about your question a little more and believe this is a better example of what you are looking to do....just creat a sheet in your workbook that would be like a navigation page (dashboard) on that page create a button labled [2009]. add the code above and then save. close and restart the work book and enable macros, click the button and watch it work.

plus the code has explanations in it for you to use. Any how hope this helps.

You don't need to close & save a work book when adding code. It will run anyway. Just close & save when finished

with the issue of names, in this case January 09 vs January 10, simply adding an underscore will make all the difference.

January_09 (make sure that both the code and the tab name reflect this)

January_10 (make sure that both the code and the tab name reflect this)


RoyUK..
the reason i stated to save close and restart, is due to the fact that some version of Excel as well as security settings will not allow you to run a macro unless you do this. Not knowing what version of Excel or what his security settings are, leads me to the safest way to test and ensure that the macro will run properly.

You don't need to close a workbook after adding code. Macros will work when added to a workbook that is open.

With 2007 you must save as a macro enabled workbook when finished
