A set field action requires the selection of a form field and a "value" that will be set into the field.
A set field action requires the selection of a form field and a "value" that will be set into the field. The "value" can be either:
A specific value that may be a number, some text, true/false, etc.
An expression that combines specific values and/or fields using arithmetic/text/logic operators and optionally parenthesis.
To support the above possibilities, set field actions support both a value entry "mode" and an expression entry "mode". Set field actions will always start in value entry mode. In value entry mode you may simply enter a number or text or if the field is a select type field, select one of the select options.
The set field actions have an overflow menu (3-dot icon) that has an option to put the input into expression input mode (see above). In expression input mode, enter specific values and/or select fields and combine them with operators and parenthesis as needed.
Here are some very simple examples:
