Hi all, tried to declare a new set with index d. Aimms complained that index d was already used BUT it is not used anywhere in aimms. I just can’t find any sets with index d. Tried also index s; same complaint from aimms. I opened another similar project and I was able to create sets with indices d and a. Not sure what’s happening. Any suggestions would be appreciated
thanks
nick
