I am having some issues with my Inventory Program and could use some help. I had the program working last night where my GUI would display the correct categories but today when I tried to get the restocking fee to add in to the value, I seemed to have messed up my file. If anyone can help that would be great.

I think my error with the file not working is in the super of the MovieDirector class since that is the only part of my file that is in red. But I also still cannot get the restock fee to add into the value field. Any ideas. Thanks

Here are my 3 files. The error I am receiving is:

Check your Dvd class constructors against the one you are trying to invoke with the super() call in the MovieDirector constructor.

Thanks, I checked and corrected my constructors and now the GUI is at least working. Any ideas how to get the restocking fee added into the total value of each dvd value?
