N Nazari,
It is not a gams related error. you should reconsidered your model and data. My suggestion is make an .lp output file ( or simply use .lst file) and start writing down your extended model on the paper and check if they are the same. If the were not, you have a chance to fix them and run again, otherwise, you should reconsider you modeling logic or data.
Best,
