I have a trigger and a test class and am in need of getting about 11 more lines covered and I'm in desperate need of help to get this.  Any help would be greatly appreciated.  I've listed the lines that aren't covered in the test below that I need help, as well as the trigger and test class.

Line 44-51

{ // Create the email attachment 
Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();
efa.setFileName(att.Name);
efa.setBody(att.body);
efa.setContentType(att.ContentType);
efa.setInline(false);
efaList.add(efa);
 }

Line 66-71
