To add a variable to your template click the ‘New Variable button’ on the right-hand Data pane, enter the name of your variable in the input field, copy the generated variable name then paste the variable into a text field.
Don't include spaces or any special characters in your variable names
When your template contains variables it’s important to test those variables with sample data to see what your documents will look like before you connect your template to a data source. Enter test values to the variable fields and click 'Save & refresh'
If this is the first time you are using 'Preview' you will see a blank version of your template in the Preview Pane as we do below.
