For each case just call another menu function and if needed pass the function the value of userSelection.

cout << "Select a team" << endl; 
cin  >> UserSelection; 

  switch (UserSelection)
{
case 1: 
cout << "New England Patriots selected" << endl; 
menu(UserSelection);
break; 
case 2: 
cout << "Buffalo Bills selected" << endl; 
menu(UserSelection);
break; 
case 3: 
cout << "New York Jets selected" << endl;
menu(UserSelection);
break; 
case 4: 
cout << "Miami Dolphins selected" << endl; 
menu(UserSelection);
break;

Hmmmm, I am not sure of what you mean.

What is menu(UserSelection); doing exactly?

When I type it up in code and define it, there's an error.

"IntelliSense: expression must have (pointer-to-) function type".

I'm not telling you to actually type it that exact code. What I am saying is you can create another function named whatever you want to call it and then invoke it for each switch case. Think of it as a sub-menu that will be called when the first menu is fulfilled. The argument (UserSelection) is being passed to the sub-menu function you create in case you need it. Otherwise you don't have to have a signature(argument) for the sub-menu function.

In the case of menu(UserSelection) , it is a function being called that would contain another sub-menu. You would need to create the function, but it would look something like this.

void menu(const string&); // Function Prototype, don't include a signature if you dont need it

void menu(const string& selection)
{
// create another menu here

}

I think I'm just trying to ask about nested switch structure. I edited my OP.
fg109 (709)
case 1: // NESTED CASE 1, CAN'T USE 1 FOR INPUT?

Why wouldn't you be able to use case 1 in the nested switch?
