Can anyone explain why the output of this:

{{ $related := false }}  
{{ if .Page.Params.lang }}  
Lang set  
{{ $related := first 3 (where .Site.Pages “Params.lang” .Page.Params.lang | shuffle ) }}  
{{ else if .Page.Params.tags }}  
{{ $related := first 3 (.Site.RegularPages.Related .) }}  
{{ end }}

{{$related}}

IS

Lang set

false

As far as I can tell, it’s because $related inside the if is a different variable than the $related outside the if. So you need this **inside** the if:

```auto
{{ $.related = whatever }}

```

The ‘.’ tells Hugo to look just outside the current scope.

No, it does not.

Thanks jmorring. That worked for me.

I have one more question, how can I get this double condition to work?

```
{{ $langs := "de fr"}}
{{ $related = first 3 (where not in .Params.lang $langs ) (.Site.RegularPages.Related .) }}
```

Assuming your frontmatter contains something like this…

```auto
lang = "en"

```

Then…

```auto
{{- $langs := slice "de" "fr" -}}
{{- $related := where (.Site.RegularPages.Related .) "Params.lang" "not in" $langs | first 3 -}}

```

Unfortunately only non english pages have that lang parameter set, so the english pages have no front matter variable for lang. So I can guess instead of checking for the value i should be checking whether it’s set.

Hmm, that looks like exactly what I need but it’s returning any results. Is `nil` check for no value or not set or both?

This will return pages where `lang` is not set in frontmatter. It will not return pages where `lang = ""` in frontmatter.

OK, not sure why but it’s not working. I don’t have that `lang` parameter set at all for most of the pages so some should be showing up.

I’d be happy to troubleshoot if you provide a link to the public repository for your project. Otherwise, I’d just be guessing…

I can’t unfortunately.

Here’s some example front matter for a page that should show:

```
    ---
title: "Page title"
description:

draft: false
authors:
- Author Name

In the site configuration file that you posted above, the first line is indented. If that’s what your site configuration actually looks like, it’s broken.

jmooring, worked it out, needed to remove the colon as it’s nested inside the if statement

```
{{- $related := where (.Site.RegularPages.Related .) "Params.lang" nil | first 3 -}}

```

Should be:

```
{{- $related = where (.Site.RegularPages.Related .) "Params.lang" nil | first 3 -}}

```

Thanks for your help 🙂
