The final layout will be based on my manuscript submitted, I just want it to be as correct as possible. Can you give me an example of the unnecessary changes. I am holding the return of the changes until have a final work that is correct since the changes cost. I am send you the final doc as in for you review. Thanks for your continued help on this. As well as the understanding of the process so next time it will go better.
