2 bugs founded

Sorry for my poor English:

Bug1:
Making a invoice uses the "buying price" instead of the "selling price" in the textEdit box

This is not a bug but an error...
500 Internal Server Error
(This happens when sending invoice via email)

Thanks in advance :D

2nd - also not sure if its a bug or a feature that seems to have been remove?? when adding a new articule cant seem to add a code for it there is no box for that.
