Topic: Unknown column 'user_level' in 'field list'

I'm going to be a pest here for a day or two... Is this a problem in the code or a problem I have (already!) created?  I got this error from http://localhost/ (I'm setting up a dummy site on localhost ready to migrate it if I can get it working).  It is true that the field user_level is only present in table 'users' so should there have been a dropdown for it when doing add agent on  http://localhost/ ?

I admit that I have not dived into the code to try to sort this out for myself.  I am still fumbling to find things in the code.
