Graph calculations

I am trying to make this sweater. Katia elegance No 76. Pattern 15.
There is a graph of the pattern. There is a center R at the bottom which means repeat. When I repeat the center part of the pattern the # of stitches do not work out at the end.
I have attached the graph and the pattern instructions. I am using the C size 123 stitches. I cannot figure this out. Can someone help me with these instructions. I could not give a picture no enough room in attachments for it.

Just figured out my mistake. I was going to C instead of starting at B in the pattern. Now it will work out.
