Hello everyone!

When running the following code,

#Part 0 declaration of parameters

param n;

param t;

set N:=1…n; # yield, years

set T:=1…t;

param r{N}; #rate of bonds

param L{T}; #liabilites

param LR{T}; #liability rates

param c{N,T}; #payment structure

param PVB{i in N} = sum{t in T}c[i,t]/(1+r[i])^(t); #PV of a cash flow stream

I am faced with the error saying:

syntax error

context: param PVB{i in N} = sum{t >>> in <<< T}c[i,t]/(1+r[i])^(t);

Any help is really appreciated!
