Strange problem when loading a table -- What did I do wrong?

I was hoping someone may be able to explain the following mysql results for me.

Created a table NO PROBLEM

mysql> desc students;
+---------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+---------+-------------+------+-----+---------+-------+
| STUDID | varchar(9) | | PRI | | |
| LNAME | varchar(30) | | | | |
| FNAME | varchar(30) | | | | |
| LEARNID | varchar(15) | YES | | NULL | |
| COMMENT | text | YES | | NULL | |
+---------+-------------+------+-----+---------+-------+
5 rows in set (0.00 sec)

Loaded data into the table from a text file. Took a few tries but seems ok.

mysql> load data infile 'C:\\INT120AW05.txt' into table brian.students
-> fields terminated by '+'
-> ;
Query OK, 34 rows affected, 34 warnings (0.02 sec)
Records: 34 Deleted: 0 Skipped: 0 Warnings: 34

BUT... When I check the data I get NULL for STUDID

mysql> select * from students;

I don't understand why I would get 3 different results for the same field.
Have you seen anything like this before??
