# Functions

Depending on the field type that you select, you can assign conditions to certain functions. For example, you can define a field that executes a macro when you click the field in the document, or a condition that, when met, hides a field. You can also define placeholder fields that insert graphics, tables, frames and other objects into your document when needed.

To access this command...

Choose Insert - Field - More Fields - Functions tab

### Type

Lists the available field types.

Type | Meaning
--- | ---
Conditional text | Inserts text if a certain condition is met. For example, enter "sun eq 1" in the Condition box, and then the text that you want to insert when the variable "sun" equals "1" in the Then box. If you want, you can also enter the text that you want to display when this condition is not met in the Else box. To define the variable "sun", click the Variables tab, select "Set variable", type "sun" in the Name box, and its value in the Value box.
