Hello,
i have a problem combining Sumproduct and two or more IF functions, i have tried to combine the two but i am coming up with errors, here it is,
i have vendors that work throughout the week, if the vendor works on a particular day, revenue is entered against him, a very simple sumproduct formula, but i need to indentify if the vendor either doesn't work on a particular or if no revenue is entered against that day.
i have tried using an array, but i'm not that familar with what they can or can't do.
i have attached a sample file with expected results, if someone could have a look.
many thanks reg
