Hi Felix, '%(title)s' doesn't affect the table contents, it is used to represent the 'id' field in drop-down select boxes etc. In this case, the 'title' field would appear in the select box for choosing the 'id'. Of course, the idea is that the title field will be much more understandable than an id number. If you do not have a 'title' field, then use whatever else would be meaningful e.g. '%(name)s'.
