Your code should work, but you’re using your helper

```Handlebars
{{sample}}

```

in the template without passing it any arguments. Even if you’re testing to see if things work, pass it a test string like

```Handlebars
{{sample "some string"}}

```

You need to do that because you’re using the helper in a raw `hbr` template. For testing purposes, the helper should work even if you don’t pass it anything in regular `hbs` templates.

If you’re creating a block-helper, then it needs to have `#` and you need to close it like so.

```Handlebars
{{#sample}}

{{/sample}}

```

Adding `~` to your helper optionally trims whitespace between any HTML tags it returns. So

```Handlebars
{{~#sample}}

{{/sample}}

```
