Read about Variables in Aliveforms


In title of screens, calculation are executed in [/ /] block.


We have variable PER_UNIT_COST defined. In Form, we have input of type number to capture number of units on index 2.

[/ [[VAR.PER_UNIT_COST]] * [[SCREEN.2]] /]

Note that we have maintained [[VAR.]] and [[SCREEN.]] syntax.

If we want to use intermediate value

[/ 19 * [[SCREEN.2]] /]

We can also use score of screen in Analytical Form. For example, we have multiple choice screen with items. Allow multiple is on, so user can select multiple choices.

[/ [[VAR.PER_UNIT_COST]] * [[SCORE.2]] /]

We can also use calculations on Hidden Inputs. For example, we have hidden input after welcome screen. [/ /]. Before the submit screen. we can add another hidden input [/ - [[SCREEN.1]] /]. This way, we obtained total time taken by user to complete the form.
