breasking out of a while loop (in an if statement)

Hi, I wonder if anyone could be kind enough to point out what I am doing
wrong here (please see code below).
The problem arises in the last 5 lines of code. 'result' is a database
query result (type string). If it's empty then it has size==2 and if not
then it's >=3. If it is empty then I have placed a return value after
it. However, if it is not then I would like it to go back around the
while loop. The code *looks* okay...
-=---=-=--=-==-=-=-=-==
while (j!=0):
if (radiobutton=='comma'):
tempString = string.split(text[i-1], ",")
else:
tempString = string.split(text[i-1], "\t")
matric = string.rstrip(string.lstrip(tempString[0]))
SQL = "select * from STUDENTS where matric= '" + matric + "'"
result=db_conn.query(SQL)
result = len(result)
if (result>=3):
return "Student with matric value " + matric + " already exists
in the database"
# break
else:
j=j-1
-=---=-=--=-==-=-=-=-==
=> Error Type: IndexError
=> Error Value: list index out of range
I'm using Python with Zope BTW.
Can anyone see my problem? Any help would be greatly appreciated ;-)
