Project Description:
Dear Bidder

I am looking for someone to modify the attached sheet which used to measure the progress of the 3rd party using Microsoft Excel.
I have created this workbook what I need is only to include the weight in (Colum C) to the measurement. For example if contract 5 with weight of 39% is under plan for the month of August is must effect the whole progress of the 3rd Party. On the other hand, if Contract4 is under plan in August it should not drag the whole progress because it weight much less.
I just need someone to fix the formula to include the weight value of each of the contract. At the moment Colum C has nothing to do with formula and I would like include it.

This should be very simple work.

I need this work to be completed by Sunday 9-Oct-2011 at 10PM US Central Time. Thanks
