Two major issues here. First is you are not referencing either INSERTED or DELETED. And second is that your code is unable to handle multiple row modifications.

Before we can offer more detailed help you will need to provide some more details:

1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data

Please take a few minutes and read the first article in my signature for best practices when posting questions.
