$rs=mysql_query($sql,$conn) or die(mysql_error());
echo $sql.'<br><br>';

</table>
</form>
So the code selects the survey from the survey table and then gets all the questions from survey_questions for the selected survey.
Each question has up to 8 answers (all checkboxes with value of Y)
The user goes though and checks the box for the answer(s) they choose so when the form is submitted, how can i make it insert into surveys_completed table each answer.
So for each question, it adds a row in the surveys_completed table.
The structure of the surveys_completed table is:
sequence
survey_sequence
question_seq
answer1
answer2
answer3
answer4
answer5
answer6
answer7
answer8
