Pull specific data from the month selected from a list

Hi all, wondering if you can help - not sure how to search for this one in google, so came here!

I basically have a spreadsheet with sales data in, each tab represents a month. I also have a summary page which I want to be able to see a split of information at the click of a button. I have a list on this summary page with every month on the list. I want to be able to select a specific month from the list, and the data from that month appears below in the summary page. The data will be transferred from the matching worksheet. I believe a VLOOKUP may be the answer, but just a bit unsure. If you can help I'd appreciate it!

If anyone needs further clarification, please let me know

Thanks all x

INDIRECT will do it

Thanks for the reply, would you mind explaining how this would work?

Many thanks again!
