Example: A field crew is assessing an attribute...... they enter values in fields A, B, C, and D is there a way to auto sum them in Field E? The sum would be a number that meets a threshold. If that threshold is exceeded than an action would need to be taken. I am looking for a way to automate this during collection in the field so they don't have to use math. Is there a way to perform a mathematical calculation as a default for a field value?
