Custom profile content linked to database

I’d like for my members to be able to customize their own profile with fields that I create. This information should be on their regular profile so it’s viewable to other members.

I am familiar with creating a custom database. However, I can’t seem to get the form they fill out to connect with the fields on the profile, even though I have loaded the dataset and connected each field.

Is there some sort of block on member profiles?

I have tried the method of creating a dynamic page to “act” as a “member profile,” but I can’t seem to get it to be public nor can I seem to replace the wix member profile with the new page.

Any insight on either option would be very much appreciated. The tutorials I find on youtube/wix don’t seem to cover this.

Edited to add: I should mention that the entire purpose of my site is to create and be able to update custom member profiles for a game that we all play together.

Hoping to get some help.
