error 141

GAMS
1

Dear gams friends,

I have an existing gams model, and I try to extract some additional data , that I extract with some extra formulas

eq65 … dfETOH - sum(t, TP(t) * CFdf(t)) =e= 0 ;

TP and CFdf are already in the model and running. I added dfETOH to extract, but it gives me the $141 error message,

1458 display dfETOH.l
**** $141

I found in Rostenthal’s user guide that $141 means it ‘has not received any numerical values’, but I dont onderstand why not. the other TP and CFdf do have numerical values .

Can anyone help me?

Kind regards,

Benjamin

Dear Benjamin,

Instead of adding an extra equation into your model, and assuming that Tp and CFdf are variables, you can do the following:

parameter dfETOH;
dfETOH = SUM(t, TP.L(t)*CFdf.L(t));


Cheers,
Pedro
