I have a function that divides two numbers, sometimes those numbers are 0 so
the result is # DIV/0!. My second function is based on the result of the
first function. Since there isnt always data available for the first function
I get the # DIV/0! error and my final calculation wont calculate. I need the
final calculation to disregard any 0 cells or # DIV/0! errors and still
calculate the data that is available.
