Insert didn't work in Trigger

Hi i'm tring to execute an Insert and in a Trigger but it didn't work. Somebody can tell me why. Thanks

This is the code :

INSERT into DBName..TableName(Field1, Field2) SELECT i.Field1, Field2 From inserted i

INSERT into DBName..TableName(Field1) SELECT Field1 DBName..TableName WHERE Field1 NOT IN (SELECT Field FROM DBName..TableName)

(The second INSERT it is not execute)
