Consolidate the data

Hi,

I have attached a workbook named as ‘Sample’. It has two worksheets in it. They are

1.      Calculations
2.      Dump

In ‘Calculations’ worksheet, it has “Name’ column and there are two columns for each month starting from Aug ’13 to Mar ’14. In ‘Dump’ worksheet there are three columns ‘Date’, ‘Name’ and ‘Count’ and has some data is filled in each column.

With reference to the ‘Name’ columns in both the worksheet the sum of the count should be pulled up in ‘Aug ‘13’ column in ‘Calculations’ worksheet. Likewise it should repeat for all the clients and months. I have given few examples filled in for your reference.

I can use a vlookup to fetch the data from the other sheet. However, a macro  / formula (other than vlookup) doing this would really help me. Once I paste the data in ‘Dump’ worksheet and click on a button then values should reflect in respective cell. Please do the needful.

Thank you,
Prashanth
