Facing too many problem


Sir
I have just posted previously today that it shows error while submitting …I have already completed topic 1 n topic 2 …I am unable to complete the topic 3(i.e. only 1 question left) after that my course will be over…so that I went for the HINT and SEE ANSWER option available in that question and for that some points also already deducted. But now while I used that code ; it shows also an error msg. Please help me…
