I believe the problem is that you put the statement in the "data"
section. It might be that you did not define the set T in the "model"
section.
The option that I generally use is to have the first part (the "model"
part) of the code like:
param NumOfPeriods;
set T:= 1.. NumOfPeriods;
And in the second ("data") section like:
param NumOfPeriods := 6;
That way, you keep the flexibility of having the set size be
data-driven, and you could re-use the parameter NumOfPeriods in other
calculations.

This statement specifies T as a set containing the only element "1..6".
The correct specification is the following:
set T := 1 2 3 4 5 6;
