Set Field Value Action

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:

Expression Operators

The following operators are supported in expressions. Parenthesis are also supported for numeric expressions.

Operator	Name	Purpose	Example
+	Addition	Add two numeric sub-expressions	a + b
-	Subtraction	Subtract two numeric sub-expressions	a - b
*	Multiplication	Multiply two numeric sub-expressions	a * b
/	Division	Divide two numeric sub-expressions	a / b
+	Concatenation	Concatenate two text sub-expressions	firstName + " " + lastName
==, ===	Equality	Compare two sub-expressions for equality	a == b
!=, !==	Inequality	Compare two sub-expressions for inequality	a !== b
>	Greater than	Compare two sub-expressions for greater than	a > b
>=	Greater than or equal	Compare two sub-expressions for greater than or equal	a >= b
<	Less than	Compare two sub-expressions for less than	a < b
<=	Less than or equal	Compare two sub-expressions for less than or equal	a <= b
