The same residual in two equations

Hi, I’ve been modifying Mr. Pfeifer’s code for the first model ( SGU_2003.mod) of Schmitt-Grohe & Uribe “Closing small open economy models” . I want to derive the model in levels from exponential model. But it gives me the same residual in 2 equations, How can I fix this issue?
Thank you so much.
Here is my code: sgu_level.mod (3.3 KB)

Please move one variable at a time when taking out the exp().

Dear professor, can you please describe the issue in more details?

It seems you simply deleted the exp() I put in the mod-file, but did a mistake somewhere. Debugging this is hard. I was suggesting to remove the exp-substitution for one variable at a time. That way, you know for which variable the problem appears.

ok, thank you so much, I’ll try to do that
