Hi Shrivallabha ,
Thank you for the praise , especially when it comes from an Excel Ninja.
I have seen that most forums provide solutions ; in fact , a lot of solutions I post are either links to solutions which have been provided in other forums even a decade back , or copied from such solutions ; there are very few solutions I have devised on my own.
I have therefore made it a point that I will do what I do best viz. explain. Hopefully such explanations will ensure that people do not approach a forum with questions , since the purpose of explaining a technique is to ensure that anyone reading it can apply it on their own.
The Challenges section of this forum , and many others , are full of techniques waiting to be explained ; some day I will be able to sit with them and bring them back to life !
