"possible loss of precision, found double, required int" HELP

I need these variables to be doubles but it keeps saying an integer is required. My code does not have one integer so I cant have declared something wrong anywhere. Am I doing something wrong in the switch statement?

Here's my code:

Can you post the text of the error message that shows the source line with the problem?

You can get rid of some of the error messages by using a cast to tell the compiler that you want to convert the double to int.

Here's a screenshot of the error. As you can see I've tried what you said and type casted it and still no joy :(

Did you do the cast where the error is happening?

Where do you use the bet1 variable? You set bet1 to the value of bet before you assign a value to bet.
Don't you want to use the current value of bet and not the initial value?
The cast you have was done when the class was created. The value that bet has then is not related to the value of bet when your program executes.
