Your right, it is supposed to be (1-Y).  I will have to change the code to
read:
  call _OP6TOOP2
  call _OP1SET1
  call _FPSUB
  call _FPMULT
  call _OP5TOOP2
  call _FPMULT

Thanks for helping me with that but that still doesn't answer my question
about the overflow error.  Anyone have an idea about the overflow error?
