Pvit table running totals from multiple data sources

Hi guys

I'm am attempting to create a pivot table using multiple data sources. Each data source is the same type of data. What I need to do is create one pivot table to do a running total of each data source column. As an example I have a data table named January where I have a column titled number of new students. I also have the same column title for a data table named February. What I need the pivot to do is do a total of January's number of new students with February's.

is this achievable? I've attached a sample spreadsheet for info.

Thanks in anticipation of any help.

Regards
