帮忙看看这段lingo代码有什么错误，该怎么改

网上的代码 运行不起来
model:
sets:
cheng/1..26/:l,w,x,y,a,b,x1,y1,a1,b1;
endsets
max=obj;
obj=x1(i)*y1(i)+a1(i)*b1(i);
@for(cheng(i):x1(i)<=x(i));
@for(cheng(i):y1(i)<=y(i));
@for(cheng(i):a1(i)<=a(i));
@for(cheng(i):b1(i)<=b(i));
@for(cheng(i):w(i)*y1(i)+l(i)*a1(i)<=1650);
!@for(cheng(i):l(i)*x1(i)+w(i)*b1(i)<=2100);
@gin(cheng(i):x1(i));
@gin(cheng(i):y1(i));
@gin(cheng(i):a1(i));
@gin(cheng(i):b1(i));

你好，答案如下所示。

sets:
cheng/1..26/:l,w,x,y,a,b,x1,y1,a1,b1;
endsets
max=obj;
obj=@sum(cheng(i):x1(i)*y1(i)+a1(i)*b1(i));
@for(cheng(i):x1(i)<=x(i));
@for(cheng(i):y1(i)<=y(i));
@for(cheng(i):a1(i)<=a(i));
@for(cheng(i):b1(i)<=b(i));
@for(cheng(i):w(i)*y1(i)+l(i)*a1(i)<=1650);
@for(cheng(i):l(i)*x1(i)+w(i)*b1(i)<=2100);
@for(cheng(i):@gin(x1(i)));
@for(cheng(i):@gin(y1(i)));
@for(cheng(i):@gin(a1(i)));
@for(cheng(i):@gin(b1(i)));

data:
l=865 857 804 857 857 804 804 804 804 804 804 804 804 865 762 715 680 675 667 655 647 667 580 552 551 527;
w=857 715 746 675 667 663 661 639 631 563 536 535 551 446 446 446 446 446 446 446 446 426 446 446 446 426;
x=2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 3;
y=1 2 2 2 2 2 2 2 2 2 3 3 2 3 3 3 3 3 3 3 3 3 3 3 3 3;
a=1 1 2 1 1 2 2 2 2 2 2 2 2 1 2 2 2 2 2 2 2 2 2 2 2 3;
