Excel 2007 : Consolidating Monthly Sheets via Pivot Table

I have created 12 excel worksheets named January, February...- December, each sheet containing a monthly report with data on working hours, overtime, injuries etc.
Now i want to create a 13th sheet (a front page) where i can choose a month in a pivot table and then have the data from the chosen month (=worksheet) presented in a table below.

How do i do this???

I tried using the IF-function, but this demands too many arguments (12) - at least the way i tried...

Can this be done in Excel or do I have to use Access?
Anyone?? Your help will be much appreciated.
Tnx

If each of your sheets are identical you might be able to get away with a Multi Consolidation Pivot Table (with Sheet as Page field)

Better to post a small sample file which reflects your data.

On an aside I appreciate you changed your title but it was still not ideal (ie "need help" adds no value and reduces effectiveness of search functionality of the board)... I altered according to your requirements.

Given your file you can probably just get away with using INDIRECT if indeed you only ever want to return a single month - ie recreate that sheet.

For ex. if F1 = March then

D5: =INDIRECT("'"&$F$1&"'!"&CELL("address",D4))
copied down etc...

If you're looking to aggregate (ie January:March) you can use 3D Summation but that will require a little more work.
