Referencing site members' personal pages on a repeater element they created through a form?

Preface: I am not versed in very much coding at all, so I have relied fairly heavily on WIX’s solutions and other people’s ideas.

I am trying to figure out how to reference a site member’s personal (private) page on a repeater that shows items that have been created through a user generated form.

The form collects information through user input fields about current projects that site members are doing, then displays them on a dynamic collection page (and item pages obviously).
The repeater displays the name of the project, as well as a photo, the creator, the date(s), location, and a brief description. (Also a button to view the item page).
I need the “creator” text (which is technically a button) to link to the member who created that project’s personal profile page.
I tried hooking up the Members/PrivateMembersData dataset on the dynamic collection page and connected the “creator” button to that dataset, filtered to the user who created the item, but then I realized you can only hook up an element to one dataset at a time, and I also need the button to display the text from a certain field in my “projects” dataset. Before I went any further I thought I’d ask if there’s a better way to do this.

So really, all I want is for a button to display text from one dataset, while navigating users to a page referenced from another dataset.

I’m sure you can do this with code or maybe even without, but I just don’t know how.
Many thanks in advance if you do!

When you talk about ‘site member’s personal (private) page’.

Do you mean a page from the Wix Members app itself.

Which will add the collection called Members/PrivateMemberData automatically and that collection will only let the site member read use their own row of data and nothing else.

Or their own profile page as shown in this tutorial here.

It doesn’t matter really which one you are talking about as they are both accessible only to that unique site member who is logged in.

However, you can using code get around this by using Wix Data Options in your Backend and suppressing any checks, you can see more about here.
