请教下Mplus 报错：*** ERROR in MODEL CONSTRAINT command
  The following parameter label is ambiguous.  Check that the corresponding
  parameter has not been changed.  Parameter label:  A1

这个错误实在是找不到在哪里，请教下该如何解决。

Mplus语句如下：
DATA: FILE = D:\1.txt;
   VARIABLE: NAMES are x mo xsq me y ;
   usevariables are x mo xsq me y ;
   ANALYSIS:
   BOOTSTRAP=5000 ;
   TYPE=RANDOM;
   ALGORITHM=INTEGRATION;
   ESTIMATOR=ML;
  MODEL:
  me on x (a1)
      xsq (a2)
      mo (a3)
      x*mo (a4)
      xsq*mo (a5) ;

  y on x (b1)
   xsq (b2)
   mo (b3)
   x*mo (b4)
   xsq*mo (b5)
   me (b6) ;
[y](i1);

  MODEL CONSTRAINT:
   NEW (T11 T12 T13 T21 T22 T23 T31 T32 T33) ;
   NEW (x1 x2 x3) ;

   x1=6.32 ;
   x2=5.42 ;
   x3=4.52 ;

      T11=b1+b6*a1+6.35*b6*a4+x1*(2*b2+6.35*b4+6.35*2*b5+2*b6*a2+6.35*2*b6*a5);
      T12=b1+b6*a1+6.35*b6*a4+x2*(2*b2+6.35*b4+6.35*2*b5+2*b6*a2+6.35*2*b6*a5);
      T13=b1+b6*a1+6.35*b6*a4+x3*(2*b2+6.35*b4+6.35*2*b5+2*b6*a2+6.35*2*b6*a5);
      T21=b1+b6*a1+5.40*b6*a4+x1*(2*b2+5.40*b4+5.40*2*b5+2*b6*a2+5.40*2*b6*a5);
      T22=b1+b6*a1+5.40*b6*a4+x2*(2*b2+5.40*b4+5.40*2*b5+2*b6*a2+5.40*2*b6*a5);
      T23=b1+b6*a1+5.40*b6*a4+x3*(2*b2+5.40*b4+5.40*2*b5+2*b6*a2+5.40*2*b6*a5);
      T31=b1+b6*a1+4.46*b6*a4+x1*(2*b2+4.46*b4+4.46*2*b5+2*b6*a2+4.46*2*b6*a5);
      T32=b1+b6*a1+4.46*b6*a4+x2*(2*b2+4.46*b4+4.46*2*b5+2*b6*a2+4.46*2*b6*a5);
      T33=b1+b6*a1+4.46*b6*a4+x3*(2*b2+4.46*b4+4.46*2*b5+2*b6*a2+4.46*2*b6*a5);

  OUTPUT: CINTERVAL (BCBOOTSTRAP);
