Summary
This article covers the Compute Value Conditional Action. The Compute Value allows a User to build an assortment of arithmetic operations with a variety of operands.
You do not need a trigger field to fire a compute button. The calculation will always fire on save or if you hit the calculator icon next to the field to be computed. See Fig 2, for an example of a calculator for the Datatrak Direct web.
1) When a user selects the Conditional Action type Compute Value
2) A dialog box opens at the bottom of the Conditional Actions Builder as shown in the figure below.
The example below is a compute for age.
Fig 1
Operators are as follow:
- = Subtraction
* = Multiply
/ = Divide
, = Comma (operator)
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
Example: Weight = 220 lbs, Height = 6’0″ (72″)
Calculation: [220 ÷ (72)2] x 703 = 29.8
Fig 2
The example below is a BMI calculation on the web
The example below is a BMI calculation on the Mobile application
Another way is to do a scoring field on the web is to add up the fields as shown below in Fig 3 below:
The condition will look like Fig 4 below: Notice how there are no trigger fields used. The calculator next to the field will compute, or on save of form, it will always compute.
When using a Compute Value Conditional Action, and assigning calculations based on other form fields, note that •Zero cannot be assumed for a blank value (use blank instead of assuming 0 when the field is blank) •All fields that are assigned to the computation formula should be marked as required
