I have created a form of type user with about 40 fields. Most of the fields should be stored in the db.
While the form works fine, there is still an issue with one of the fields and I don't know how to go on.

It is of type "text" and has the name "user_konto_inhaber". After sending the form, the user entry is successfully saved and the corresponding mail reports the values of all fields - except for this one. This field will report the name of the field instead of its value.

This usually is a configuration problem, but I don't find the position ;-).

I made some screenshots to illustrate the parameters:

Here is the definition of the field:

Here is the message prototype of the email, the fields are printed as table:

Here is the snippet of the email, that is sent, the field-name is not replaced by the value:

If I go to the backend and edit this new user, then I will find the field entry in the tab profile:

conclusion: The field is defined in the database and filled with the user entry, but the field name is not recognised in the mail message prototype.

It is likely, that my infos are incomplete for You. What else is needed or what is wrong here?

Thx a lot in advance :-)
