I use the the following  dtml commands to populate the db.

<snip>

        <dtml-call "REQUEST.set('counter', REQUEST.SESSION['counter'])">
        <dtml-call "REQUEST.set('loop_counter_temp', '0')">
        <dtml-call "string_to_int(loop_counter_temp ,REQUEST)">
        <dtml-call "REQUEST.set('loop_counter', y)">
        <dtml-call "REQUEST.set('loop_counter', 1)">
 <dtml-in expr="_.range(counter)">
  <dtml-call "REQUEST.set('student_score1', 
student_score1_temp[loop_counter])">
  <dtml-call "REQUEST.set('student_score2', 
student_score2_temp[loop_counter])">
  <dtml-call "REQUEST.set('student_score3', 
student_score3_temp[loop_counter])">
  <dtml-call "REQUEST.set('student_score4', 
student_score4_temp[loop_counter])">
  <dtml-call "REQUEST.set('student_score5', 
student_score5_temp[loop_counter])">
        </dtml-in>
        <dtml-call expr="create_holistic_score_record(REQUEST)">

But these are the results:

REQUEST
form
student_score1_temp ['2', '2', '2', '2', '2', '2', '2', '2']
Submit 'Submit'
student_score2_temp ['3', '3', '3', '3', '3', '3', '3', '3']
student_score3_temp ['3', '3', '3', '3', '3', '3', '3', '3']
student_score4_temp ['4', '4', '4', '4', '4', '4', '4', '4']
student_score5_temp ['5', '5', '5', '5', '5', '5', '5', '5']
</snip>

I can't figure out what your dtml prior to the loop is trying to accomplish, 
however inside the loop your 'loop_counter' variable is a constant value (it 
does not change, so you keep referring to the same list element).  You need 
something like:

 <dtml-in expr="_.range(counter)">
     <dtml-call "REQUEST.set('student_score1', 
student_score1_temp[_['sequence-item']])">

The _['sequence-item'] will contain the current iteration result of your 
_.range(counter) statement.

Better yet, do this in a python script (way easier).
