lingo程序，这里哪里错了，提示是错误11.sets:这里的冒号有错

Question

sets:
residents/1..5/:top,bottom;
ku/1..4/:kucun;
link(ku,residents):price,x;
endsets
data:
b0tt0m=30,70,10,10,10;top=80,140,30,50,30;
kucun=50,60,50,30;price=160,130,220,170,150,140,130,190,150,170,190,200,230,99999999,120,120,180,200,150,150;
enddata
min=@sum(link:price*x);

@f0r(ku(i):@sum(rsidents(j):x(i,j))=kucun(i));
@for(residents(j):@sum(ku(i):x(i,j))>b0ttom(j));
@for(residents(j):@sum(ku(i):x(i,j))<top(j));
end
