Merhaba aşağıdaki formül yazım hatası vermektedir neyi yanlış yapıyorum acaba yardımlarınızı rica ederim

x1 : =mov(c,4,s) ;
x2 : =ref(mov(c,4,TRI),-8);
X3 : =ref(mov(C,4,S),15);
y1 : =mov(c,4,s);
y2 : =ref(mov(c,4,TRI),-10);
y3 : =ref(mov(C,4,S),18);
z1 : =mov(c,4,s);
z2 : =ref(mov(c,4,TRI),-12);
z3 : ref(mov(C,4,S),22);
m1 : =mov(c,4,s) ;
m2 : =ref(mov(c,4,TRI),-14);
