CPXERR_EXTRA_FX_BOUND
1454 Line %d: 'FX' bound type illegal when prior bound given.
      
 A column with either an upper or lower bound 
 previously assigned has an illegal FX 
 bound assignment. Since the FX bound type 
 fixes both upper and lower bounds, no additional 
 bounds can be specified. Check the MPS file.
