# Boolean

Drag a boolean type onto the canvas and assign a boolean value to it to use it as a variable. Use the SetValue to change the value further below in your Function.

A boolean type can be set to `true` or `false`. The default value of Boolean is `false`.

{% hint style="warning" %}
**Important**\
A Linx boolean type can only be populated with `true` or `false` (all letters in lower case). It does not accept any other value or variation of true/false like Y/N, Yes/No, 1/0, on/off, TRUE/FALSE or True/False.
