# Attribute interpolation

With attribute interpolation, you reference an attribute in a field. The system resolves the value of the referenced attribute, replacing the reference with the value itself.

## About this task

You can use attribute interpolation in any field that has the label icon, shown below.

## Steps

1. To reference an attribute in one of these fields, type two open curly brackets (`\{\{`) to open the attribute tree menu. Continue typing the full path to the attribute or select each level of the attribute in the attribute tree menu.
