This action allows you to store a value inside a variable or a custom field. It is very useful when you want to collect data from your users.
The different types of value After clicking the Set Custom Field action, you choose which custom field needs its value updated.
You can enter some data or even another custom field as the value.
If you need to create a new custom field, just type the name and choose the type of custom field you want to create.

The "input value" operation is used to assign a value to a variable. It works for any type of variable.
Note
TIP - the "input value" for a text variable can be used to join several text variables. See in the image below where to put the original value and the operation value.
With this operation, you can now calculate formulas directly in the Action Step - "Set Variable Value" and in the Condition Step - "Value".
Supported math operations and functions:
+, -, *, e, pi, PI, abs(), min(), max(), ceil(), floor(), log(), pow(), round(), sqrt(), sin(), cos(), tan()
Attention
Note that if the formula is invalid, the system will return 0 for the number variable and empty for the text variable.
