My requirement is....
I have a list in SharePoint 2007. When I will add a new item into that list it will check the with the previous list item in the list (only title column). If the same is available it should not allow to insert in the list and cutom error should through.
If the same title name is not in the list it should insert in the list.
As far my knowledge it will be done by event receiver. But I am unable to do it. Plaese help me.......
Thanks in advance
