Hi, I would recommend you to go through these 8 steps (Incremental approach) suggested by Jose L. Marin. Click the link given below and follow the steps. When I was working with the German Grid I had same problems but these steps really worked out in my case. I hope you will get solution. *https://www.mail-archive.com/[email protected]/msg04581.html <https://www.mail-archive.com/[email protected]/msg04581.html>*
