Hi Peter,

I have an article with a custom field named more-about
With this custom field you select another category. In this category there are more articles about this topic.

When i do: {article}[this:more-about:value]{/article} it gives the output 90 (this is the category ID which seems right)

But when i create a list of articles in this category the output is empty:

{articles category="this:more-about:value"}[title]{/articles}

Can you see if i'm doing something wrong, or maybe there is a better way to do this?
Thanks in advance.

Found the problem.
This category had no articles....

Works fine now.
