Narrative:

Center cleared us to cross merma intersection at 14000 ft. I programmed the FMC for the various intxns depicted on the tandy 2 arrival, but failed to enter the altitude at merma. The primary error here was a failure to xchk the descent point calculated by the FMC with long hand math which would have helped to discover the initial error. ATC advised it was no problem and there was no conflict.
