I have
created a web based questionnaire which contains 7 sections. I have used
asp.net 3.5 and Mysql database. At the end of each section, the data (questions
and answers) is added to the session and on the last form (final.aspx) the data
should be added to the database table called CBARQ_final. There are some null
value columns (descans2, descans4, descans5, descans7, email) in CBARQ_final.
This website
is usually running normally but sometimes I get an error message "Error-->Object reference is not set to an
instance of an object". This is not always happening. I was trying to search in
google about this message but I could not locate a good answer for my problem.
I am pasting
my code here. I shall be happy if someone can guide me to resolve the issue.
Please let me know if I am not clear or I need to provide you with more
details.
thanks
