Investment Tracking Workbook

I need a workbook to enter weekly earnings from an investment with multiple investors simplified and creating tabs that move to new pages by week showing the payouts with the first page created so I can just enter in the initial deposit of each participant then the tabs on the bottom would be week one week two etc. Also on the first page I need to be able to enter increases in deposits and have the spreadsheet auto calculate withdrawls weekly. I developed a one page example spreadsheet that needs to be perfected. Attached
