I am trying to make a subset and find out the sum of elements in the

subset. However, I am getting error $125 pl help if you can. my code

as below-:

Set

I ‘number of products’ / 1*3 /

F(I) ‘products of firm 2’ /2, 3/;

alias (I,J);

Table Data(I, *) ‘Marginal cost Data’

C

1 2

2 2

3 2 ;

Parameter C(I) ‘Marginal Cost of each firms’ ;

C(I)= Data(I,‘C’);

Positive variables q(I) ‘production vector’

M(F) ‘production vector for firm 2’ ;

Variables P ‘price’ ;

Equations

dNegprofit(I) ‘differentiation of negative profit, d(-profit)/

dq: dTC - p - q(I)*dp’

Defp ‘Demand function’

TQ(I) ‘total quantity for firm 2’;

dnegprofit(I)…

C(I) - P + q(I) =g= 0 ;

Defp…P =e= 10-Sum(J, q(J));

TQ(F)… M(F) =e= Sum(F, q(F)); (The error results in this statement)

Model Cournot /dnegprofit.q, defp.p, TQ/;

Solve cournot using mcp ;
