Tom is mistaken, you *did* pass an argument in your url tag: `{% url
'zoekopdrachten:resultaat' vraag.zoekvraag_id %}`. However, as the error
message says, the argument that you passed is being interpreted as the
empty string, which doesn't match the url pattern.
You haven't posted your models, but I suspect that the reason for this is
that there is no such attribute as `zoekvraag_id` on your Vraag model, so
`vraag.zoekvraag_id` doesn't return a value. I think you probably meant
`vraag.id`.
