I am having trouble getting my radio buttons to be acknowledged by my method for calculating the cost

I am having trouble getting my radio buttons to be acknowledged by my method for calculating the cost. My main

method just runs the GUI so I wont include that. I have here my Floor Class to get all the information about a customers order on the floor, and my GUI class. I how do I complete the radio buttons so they are factored into the cost? I was told initially the code is incomplete. I realize this. That is why I am asking. Here is my new code. First is the Floor Class, then my GUI class. How do I get my radio buttons to factor into my cost calculation (getCalculateCost method)?

Floor Class:
