You don’t want to specify specific values for the arguments, you want them to be variable names so that you can then call the function with any numbers.
Again, you don’t want to use specific numbers here, you’ll want to use the variable names you decide to use in the function parameter list.
Look closely again at the example in the instructions. The variable names they are using are param1 and param2. You can choose different names to use in your code or you can even use those same names. It’s completely up to you what names to use.
