Within FLEX, you can define variables to any string or number that you can use for computational purposes. For example, lets say you are looping through subcategories tied to a category page. On each 5th one, you want load different html. You can define a variable and reset it once the operation is complete.

{% define $x = 1 %}
{% define $myVar = ‘Hello World’ %}

Defining and calling a defined variable must start with ‘$’ just like in PHP.

To call a defined variable:

{$x}
<!-- output -->
1

{% if $x == 0 %}
I Love FLEX!
{% endif %}
