Conditionally importing Data from one of several different worksheets based on 1 factor

Hello,

I am currently working on a spreadsheet that records data from 11 different locations, with each location having it's own page within the workbook.
All of the pages are identical in terms of how the data is stored, the only difference is literally the name of each page (i.e. the location).

What I would like is to have a master page that then pulls through the relevant data, dependent on which location I choose from a drop down list on this page. As each individual page is identical in terms of lay-out, one formula will work for each page, with the only obvious exception is the page reference embedded in the formula. I know how to do a standard lookup for various figures, but I can't figure out a formula that would work with 11 different options... Is there any way to accomplish this?

Thanks,
D
