This intro problem practices IFERROR. IFERROR returns one result when a formula works and a fallback result when the formula creates an error. Update the output cells so each row divides total by groups, but returns 0 when the division would error.
See Examples
Your solution should use cell references so it updates automatically if the input cells change values.
