It could mean that there is some unfilled value or some value is not in table and so on. In this cases is better display nothing or some specific word or number instead of error value. I have prepared table containing #DIV/0 values and two ways how to solve it. The first is using formula and the second is made by conditional formatting.
The bottom table have simple formula for calculating percentage of items revenue. For example in B9 is formula =B2/B$6. So, when cells in the top table is empty, result of formula is #DIV/0. Continue reading “How to hide error values” »

This is a table with some formulas:
Let’s see how to do that: Continue reading “How to quickly lock (protect) all of the cells containing formula” »
There is problem with average for some specific values in a table. We need to make average of the items that meet several criteria. Following table represents data of some worldwide company. You can see branch offices in the cities and number of their new customers per each month and year.

There are some stuff dealers. In the following table is list of their sales. We need to know, how many sales they made from the beginning of the year.

Question is how to create running total for each dealer in the table. Continue reading “Running total for multiple items solved by array formula” »
