Hi All, I have created a simulation that works perfect and I have the results been returned in a list as I have multiple values. I then decided to include some user interaction by using the package rpanel, I now get the error: object of type 'builtin' is not subsettable when I attempted to have the return my list with the results . Any help needed. I can also upload code if needs be.
