Good Morning Ivo.
To populate the 'Table' component on your form, I assume you make use of a report-builder/data-object.
In which a query is used to select contact rows from a table, holding your contacts.
And with this query, you indeed select >1 rows from the table, right.
Which may include the logged-in user amongst others.
To have the contact row for the logged-in user, you could create another data-object with the query to select only the logged-in user details.
(select * from <table> where <userid>='<logged-in user>')
And then add a 'Text' component on the form too, to be populated with this query's result.
Thanks and kind regards, Louis van Amelsfort.
