chainline first...
See the attached link, that part about how to check chainline applies. Seems like there's a question almost every day where someone has not checked the chainline. A search should bring up many more threads. If your middle ring is less than 46mm from center, a BB spacer may be needed.
Also be absolutely sure you have a 118mm spindle.
