Need help linking to a details page

My setup:
When someone submits a form, their username appears at the bottom of the item details page (so people can see who submitted the item).

I want to link that username to the user’s profile, which is like the details page, but for a user.

This is how I have it set up:

Unfortunately, this does not work. The link just appears like this:

/item-details873#error

I’m pretty sure the link should look something like

/profile2

I tried changing it to this:

That did not work either. It tries to take you to the item, but with “profile” in front of it.

profile873

The thing is, I can get a different linked field item to work, and I set it up the same way, but this does not work.

Can you share how you have set up the username that is displayed because it appears that datasource is not a single row but multiple otherwise you would not have the option for [All]

In this screenshot you can see the different between a list of the users table and a single user

Which means your navigate to options would look like this
