Answer 1

Seems you are adding the item by code. Just verify the column name spelled properly or not.

Answer 2

When ever Events are Handled.most of them used to give column name as it is there in list/library. But I recommend before providing the column make sure that column Name and its internal Name is same.

You can get Column internal Name by using SharePoint Manager Tool
