Can't figure out why my code won't run

New to coding so I don’t understand many error codes. Can anyone with a little bit of experience tell what I am doing wrong?

?

Insertion Operator <<

The insertion (<< ) operator, which is preprogrammed for all standard C++ data types, sends bytes to an output stream object.

Extraction Operator >>

The extraction operator (>> ), which is preprogrammed for all standard C++ data types, is the easiest way to get bytes from an input stream object.

In your screenshot, you wrote:

cout << "Enter Number of Judges (4-8)";
cin >> nj;

This is correct.

But later in the code, in the if statements, you mixed up the operators.

You wrote:

cout >> "Invalid. Enter Number of Judges Again (4-8)";
cin << nj;

This is incorrect.
Same mistake in the other if statement.
