{% endhint %}

Open "Tools" menu on the form header and select "Variables" option (2):

On "Variables" popup (3) click "Add variable" button (4):

![](/files/8b088b278e34f60783d87ba1228eb3d7d3f95972)

Provide variable name (5) and click edit icon (6) to open merge field builder (7):

![](/files/676f66c8e241ebcd1ae8a9c5f1ce8bf7d67de4a8)

Select context object (8) and object field (9). Using merge field (10) and functions (11) build and expression and click "Save" button (12):

{% hint style="info" %}
For more information about working with context objects please refer following documentation chapter: [Context objects](/forms/form-building/context-objects.md)

{% hint style="info" %}
To use the functions or calculations inside of variable you have to build a formula like: `FORMULA[SQRT(4) + (2*3)]`
{% endhint %}

![](/files/e146ddb05d4d5abb5d2e66b331f665d2d45bcef5)

{% hint style="info" %}
Above expression first casts number typed value to text and then checks if final string ends with "9". It will return "TRUE" if string does end with "9" and false if it doesn't.
{% endhint %}

Save "Variables" (13) and save the form (14).
