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?

totalValue += restockFee; // add restocking fee to total value
