### edit/override of identity

Posted:

**Wed Jan 09, 2019 8:46 am**Hello,

I have a short program that compiles and solves a model for energy prices.

It forecasts a real price, and then inflates it using a GDP deflator to create a nominal price. I would like to make adjustments to the nominal price (identity) directly using the "edit/override" function. Is this possible? Currently, when I edit/override --> make changes --> reinclude --> resolve the nominal price series gets very wonky and goes negative.

Thanks,

Bob
