Calculated Field

On Builder:

App UI:

The Calculated Field is for calculating values, based on values provided or the outcome of other questions within your form.

Field Properties:


Name the field.

Set Expression:

Here you can set the expression that will determine what is calculated. A few sample expressions you can use:

Addition: SUM(sample_integer_1 , sample_integer_2 , sample_integer_3)
Subtraction: sample_integer_1 - sample_integer_2
Multiplication: sample_integer_1 * sample_integer_2
Division: sample_integer_1 / sample_integer_2 

Calculating hours worked: (Time_Out - Time_In) / 3600 

Please note, you can take this a step further and round your answer
Ex. ROUND((Time_Out - Time_In) / 3600, 2)
In this example, your answer would be rounded to the nearest hundredth.
