[Cmpl] Error

[Oscar Augusto Téllez Sánchez]

Good day,

here is my problem… when i run my program this is the message

create model instance ...
error (compiler): file biomass.cmpl line 16: syntax error, unexpected ASSIGN_ITER, expecting ':'
error (compiler): file biomass.cmpl line 20: syntax error, unexpected ASSIGN_ITER, expecting ':'
error (compiler): file biomass.cmpl line 20: syntax error, unexpected '}', expecting end of file
CMPL model generation - failed

I am following the standard and i don´t know why is asking me to put (:)  any idea how to solve it? (in bold are the referred lines)

thank you in advance ;) my code is below

Oscar

Program:
%data biomass-data.cdat : FARMS set, SIZE set, SP,TC,PC,CF[SIZE], Q[FARMS], K[SIZE],d[FARMS,FARMS], gamma[FARMS]

variables:
	#Quantity of waste treated at plant i
	X[FARMS]: real[0..];
	#Quantity of waste send from farm j to plant i
	XS[FARMS,FARMS]: real[0..];
	#1 if plant i is installed with capacity k
	Y[FARMS,SIZE]: binary;
	#1 if we send waste from farm j to plant i
	W[FARMS,FARMS]: real[0..];

objectives:
	Profit: sum{i in FARMS: (SP-PC)* X[i] } 
		+ sum{i in FARMS, j in FARMS : TC * XS[i,j] * d[i,j]}
		+ sum{i in FARMS, K in SIZE : Y[i,k] * CF[k] } ->max;

constraints:
	#Maximum one plant per site
	nPlants {i in FARMS : sum{k in SIZE: Y[i,K]} <= 1;}
	
	#A farm can only send to one plant
	exclusivity {i in FARMS : sum{j in FARMS: W[i,j]} = 1;}
	
	#You can send to i only if there is a plant there
	cond1 {i in < FARMS: sum{j in FARMS: W[i,j]} <= sum{k in SIZE: Y[i,K]};}
	
	# Equivanlence between what is send (waste) and what is produce (methane)
	equivalence {i in < FARMS: gamma[i]*X[i] = sum{j in SIZE: XS[i,j]};}		
	
	#Production capacity
	ProductionCap {i in < FARMS: x[i] <= sum{k in SIZE: Y[i,K]*KP[K]};}
	
	# you cannot send more than farm´s capacity
	farmsCapacity {j in < FARMS: sum{i in FARMS: X[i,j]} <= sum{i in FARMS: W[i,j]*Q[j]};}
