Uncontrolled set entered as constant

GAMS
1

Hi
I am new to GAMS and want to use it for partial equilibrium modeling. Supply shouldn’t exceed the capacity of the mine. So I put the following code:

Positive Variable
s(n) ‘supply’;
Parameter Capacity1(n) /one 20,two 20, three 20/;
Equation
Capacity ‘maximum mining capacity’;

Capacity… s(n) =l= Capacity1(n);

which gives the error: ‘Uncontrolled set entered as constant’

what mistake am I making? Many thanks in advance.

Equation
Capacity(n) ‘maximum mining capacity’;
Capacity**(n)**… s(n) =l= Capacity1(n);
