Hi Zain Khan,
Few important points to be noted before we post any question to SCN forum/Space.
Please use right space. This question is belongs to MM, you would get proper and correct guidance, if you post to relevant spaces.
Second, It is always good, if you mark your post as a question than discussion.
Hope you will not take me wrong.
