i have this tuple:

 for 1 in 1..Periodos do
      SumaVariables7_1=for M in 1..Salas collect:Collect do
			  for  W in 1..5  do
			     {Collect X.M.W.1}
			  end
		       end
in
      {FD.sum SumVariables7_1 '=<:' 0}
end

and this another tuple


for 1 in 1..Periodos do
      SumaVariables7_2=for M in 1..Salas collect:Collect do
			  for  W in 6..7  do
			     {Collect X.M.W.1}
			  end
		       end
in
      {FD.sum SumVariables7_2 '=<:' 0}
end
