Error 66 even when all symbols are defined and assigned... help!

GAMS
1

I checked other subjects related to error 66 but I couldn’t find an answer for my problem. I get the following:

66 The symbol shown has not been defined or assigned
A wild shot: You may have spurious commas in the explanatory
text of a declaration. Check symbol reference list.
256 Error(s) in analyzing solve statement. More detail appears
Below the solve statement above
299 Unexpected end of file

The problem is in the objective function. It does not say which symbol is undefined or unassigned.

I used "$onSymXRef " to check if everything was declared and defined and it was perfect. Why am I getting the same error? Here is my code and the include files.

HELP ME, PLEASE!

Hi,

If you look into the listing file, the first error you get is

****  $66,256,299  UNEXPECTED END OF FILE (1)

**** 3 ERROR(S)   0 WARNING(S)

After adding a semicolon after the solve statement yo get

79414  solve MEPI using mip minimizing of;
****                                     $66,256
**** LINE    251 INPUT       C:\Users\user\Documents\support\mepi\MEPI.gms

You might want to assign values to CA and then it should work.

Thank you so much! It worked! I thought I had assigned all values…
