Both models aim to introduce loss-aversion preferences into the life-cycle model.
The following are the error messages from the LifeCycleModel38.

use parentheses. Otherwise, check for mismatched delimiters.

The following are the error messages from the WorkshopModel11. The WorkshopModel12 for ambiguity aversion shared the same errors.

Fixed WorkshopModel11 and WorkshopModel12. Was all very minor stuff. Thanks again. That is all of them working 🙂
