Summing function in forms does not work consistently.
A form has two column in the grid. Each column is summed in the form footer field. Sometimes a column sum is calculated and sometimes not.
Some rows do not have a value in the field to be summed. This usually occurs when a field is blank.
The summing function assumes that all fields to be summed have a value, even if the value is 0 (zero). The ensure that the field has a value, set the default value to 0 in the control. That way the summing function will always see a “number” and function as expected.
