Help with Business Finance

the business plan of this small family invented business is already done, but I can't balance it! BALANCE SHEET: it has to be balanced monthly, so lines 29 and 37 have to be exactly the same! SUMMARY: in summary sheet, the balance sheet annual has to be balance, so lines 64 and 72 have to be exactly the same. INTRODUCTION&ASSUMPTIONS: this sheet contains my assumptions for the costs that I used, so in the profit and loss, cash flow and balance sheet the data come from “introduction&assumption” sheet. You can see the all the costs involved in “introductions and assumptions” column P to T. SALES FORECAST: it is correct and how the professor wants RATIOS: it is correct and how the professor wants. The sheet will be updated once the sheet SUMMARY will be balanced. BALANCE SHEET PROFE: is the model that professor gave us to do the balance sheet monthly, so he wants the sheet “ BALANCE SHEET” as his model that you can see in BALANCE SHEET PROFE. GRAPHS: check if they are correct once you have balanced the balance sheet and summary. Add others graphs that can be useful to understand the overall situation trend. **** PROFIT & LOSS, CASH FLOW AND BALANCE SHEET HAVE TO BE LIKE I HAVE DONE, I MEAN FOR THE STRUCTURE, BECAUSE PROFESSOR WANTS LIKE THIS! Change whatever you want to obtain a balance sheet and summary balanced, but not the structure of the 3 sheets aforementioned, because professor wants like this.
