The problem is the OP either:
1. Post a very generic question or title such as "please help" or "not working" without providing anything else
2. Never read the guide of posting question on forum
3. Post an error message with info pointing to line number causing the error but no code to refer to
4. Posting sample code which looks fine and the actual issue is somewhere else that the OP has ignored
It is quite frustrating sometimes. In first few replies, we were patiently trying to help. But, after a few posts, still not getting to the point.
They never thought if they put on the same shoes, their turn to try helping someone who do the same as above,
or maybe they thought other people on another part of the world is sitting next to him/her looking at the screen or just can read their mind.
Some errors are due to many possibilities. There is no one-to-one root cause to all issues.
