How can i change my AMPL mod/data file for Capacity to not get syntax error - ampl

Question

My problem from NEOS server comes out as:
amplin, line 16 (offset 239):
syntax error
context: param Capacity{i in >>> 1...m <<< };
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Data is:
param m := 4;
param n := 30;
param Facilitycost:

My model is:
param m; #number of facilites
param n; #number of customers needed to be served
param Facilitycost{j in 1..n, i in 1..m};
param Capacity{i in 1...m};
param Demand{j in 1..n};
#THE DECISION VARIABLES
var AllocatedFacility{j in 1..n, i in 1..m} binary;
#OBJECTIVE FUNCTION
minimize Total_AllocationCost: sum {j in 1..n, i in 1..m}:
Facilitycost[j,i] * AllocatedFacility[j,i];
#THE CONSTRAINTS
s.t. CapacityConstraints {i in 1..m}:
Demand[j] * AllocatedFacility[j,i] <= Capacity[i];
s.t. AllocatedFacilityContraints {j in 1..n}:
sum {i in 1..m} AllocatedFacility[j,i] = 1;
How can i change Capacity as such that the condition is met as wanted for the colum i?
Is the problem in the data of in the model?

Answer 1

The syntax error for this line is because you have 1...m where you should have 1..m.
