Added those three fields to the interface. Took me a while to get gender working. When a gender was specified, the gender field in each record appeared. When the gender was not specified, no value appeared in the gender field for each record. I had been asking to display the p_sex field from the exams table (which should have been an integer). When I asked instead to display the gender_text field from the genders table, everything worked perfectly, even though the gender_text value is obtained by a lookup from the p_sex value. I don't get it.

The next two fields went in no problem.
