    I am not getting a total unless all fields have a value.

    Asked by pennistritter on January 31, 2014 at 11:10 PM

    I am not getting a total unless all fields have a value. What if one field is left blank? How do I get the total to show then?

    Hello pennistritter,

    This is because the computation will not perform the exact formula unless all fields involved are filled or has a value.  As a result, all fields will be required to be filled up before you can get a total.  

    You can however set your form's fields to be required so that all fields will be filled up properly. Simply look for the Required option on the tool bar of your form builder.

    Please let us know if you have further questions.

    I need to calculate the average of some fields value.  Some of these fields may be left blank.

    In normal situation, the value of blanked fields are 0. 

    How can I exclude blanked fields  from calculation?
