@nukkumatti thanks for your reply.
I've put a textfield control (excuse me when names are different, I have a dutch version and have to translate) called "infopath" on the form. As default value I toke a string and put "testvalue" inside it.
In the library I also made a column named "infopath".
I then used the publication wizard. Let it make a new form library en attached the "infopath" column/fieldvalue.
In sharepoint I added the form library to the page. Filled in the new availabel form. Pressed the magic button and see...
The form shows up in the library as it should. But no value is filled in the "infopath" column. Where am I going wrong?
