Hi,
Thanks for letting me know. If I need explanation for an answer, I copy and paste the question in the "search" box, hence I get solutions. But, there are some questions for which I am not able to find answer and explanation, please let me know where I should post the question for seeking solutions. There are many many threads in the PS subforum, I am not knowing where to post my questions. Please help me out!
