I've been working on a file all day trying to figure out how to get the sum of multiple rows from one workbook imported into another workbook searching for the same value. The value column I'm looking at is called "PMATT"/"Request ID" for the month of January. I need to pull in the sum of January by "PMATT" value from one workbook into the other. PLEASE HELP!! Both files are below...

THANKS :-)Copy of PMATT CBV by month 2013-01-21-15-19-55.xlsx2013 Business Capital 1-16-13 (2).xlsx
