Dear GLPK builders,
when I try to run my code which have the following line, I receive
error:


for{(m,i)in arcs, b in source,t in sink,(i,j) in arcs, k in source,l in
sink: i in nodes diff source and j in nodes diff sink  }: if
Flow[i,j,k,l]=1 then Flow[m,i,b,t]=1 else Flow[m,i,b,t]=0;


Please help me to correct it.
Thanks a lot
