Please post again line by line.
In any case, use FCFF for net cash flow, IIRC it is
NetIncome + NonCashCharges + (1-TaxRate) * Interest  - CapEx - OpEx
In your example, for each year
NetIncome = net profit
NonCashCharges = depreciation
TaxRate = taxation / gross profit
Interest - may be 0, may be hiding in the Expenses
CapEx - may be 0, may be hiding in the balance sheet (end net PPE - beginning net PPE)
OpEx = closing stock + purchases - opening stock
