Create and document a model to produce an asset depreciation table for a fixed asset using both the SLN (Straight line depreciation method) and DDB (Double declining balance depreciation method) functions within VBA. Use dialog boxes to get the user inputs. The program should validate the user input for reasonableness and ask the user to modify any input that is not appropriate. For output, use a predesigned worksheet with labels, table headings, formatting and so on
