Final answer:
The Excel formula required in cell M11 should use the IFERROR function to provide a blank result if an error occurs and should be formatted as Accounting. The exact formula used for the calculation would depend on the details of the price and discount information.
Step-by-step explanation:
To calculate the total amount due after discounts in cell M11 and handle any errors that might occur during the calculation, you would use an Excel formula with the IFERROR function. This function allows for a cleaner presentation of data by returning a specified value (in this case, a blank value) if an error is encountered.
The formula might look something like this:
=IFERROR(YourFormulaHere, "")
However, without the specific details of the formula you're using for the calculation (like 'YourFormulaHere'), it's impossible to provide the exact formula you need to enter. Typically, this formula would reference other cells that contain the price and discount information. Make sure to format the result as Accounting in Excel to align the currency symbol and the decimal point.
After entering the formula in cell M11, you would copy it down to cell M34 to apply it to all rows in that range.
