There are a few very important rules to remember when adding templates to YAML:
1. You **must** surround single-line templates with double quotes (`"`) or single quotes (`'`).
1. It is advised that you prepare for undefined variables by using `if ... is not none` or the [`default` filter](https://jinja.palletsprojects.com/en/latest/templates/#default), or both.
1. It is advised that you prepare for undefined variables by using `if ... is not none` or the [`default` filter](https://jinja.palletsprojects.com/en/latest/templates/#jinja-filters.default), or both.
1. It is advised that when comparing numbers, you convert the number(s) to a [`float`](https://jinja.palletsprojects.com/en/latest/templates/#float) or an [`int`](https://jinja.palletsprojects.com/en/latest/templates/#int) by using the respective [filter](https://jinja.palletsprojects.com/en/latest/templates/#list-of-builtin-filters).
1. While the [`float`](https://jinja.palletsprojects.com/en/latest/templates/#float) and [`int`](https://jinja.palletsprojects.com/en/latest/templates/#int) filters do allow a default fallback value if the conversion is unsuccessful, they do not provide the ability to catch undefined variables.
