I dont understand why is it not working as i have limited knowledge ...I would try to get help from my seniors....Thank you for your help
Yes you have limited knowledge. But you also have an explanation. So that's not a very good excuse anymore.
Have you tried formatting the code so you can see where the blocks line up? Or are you just going to keep going on about how you have limited knowledge? If that's your plan then give up, that never got anyone anywhere.
