MySQLdb: ValueError Something Stupid

I have just started with python and MySQL.

I have a simple test for each of my tables.

The first two work as expected, but the third 'qlooks', gives a
ValueError.

If I copy and paste the SQL in the traceback to phpMyAdmin, it works
as expected.

Can anyone give a clue as to what I am doing wrong

Python 2.4
MySQL  4.1.22-standard

The tablename qlooks is LOWERCASE

Code =======================================================
	cursor = gv.conn.cursor()
	queries = ["%septi%"]
	fields = ("qlTitle", "qlSubTitle", "qlPostCode", "qlMap",
"qlDetails")
	tblFields = "select * from qlooks "
	whereTests = 'Where qlTitle like "%septi%"'
	sql = tblFields + whereTests
	#cursor.execute(sql)
	cursor.execute('select * from PERMS')
	row = cursor.fetchone()
	print "Row=", row, gv.nl
	cursor.execute('select * from LISTS')
	row = cursor.fetchone()
	print "Row=", row, gv.nl
	cursor.execute('select * from qlooks')
	row = cursor.fetchone()
	print "Row=", row, gv.nl

	cursor.close()
