Matching and Indexing Multiple Columns

Hello again!

Here is my issue. I have a workbook with thw sheets. One will have 48 columns in the end, 4 for each month of the year. I have attached a sample workbook with twelve columns for reference.

I need to pull the 4 monthly columns of data to the Monthly Data sheet. I can do this with Match and Index for one column but can't get it to work for all four.

What can or do I need to do to make this work? Any help will be appreciated.

Tim
