App Formula not been printed in the column even dow

[Alejandro_Lamo1]

I have a formula that adds, I said of columns.

The calculations were perfectly when it is tested, but it is not registered in the right column even in the test. The value on the left hand side appears, but not the volume in the column.

Please Help

The test was right

What is the formula? What columns does it involve? Which column is the formula located? What is the formula supposed to do?
