    Angry Getting error using an enum in an if statement???

    Hi, i'm trying to make a simple C++ program in which the user must try to guess a number, if they guess too high it says "too high" and if they guess too low it says "too low".
    I also decided to add a feature which allows them to select how many tries they would like to guess the number. I tried to make "tries" type an enum so if the user could not pick an invalid number but for some reason i cannot use it in an if statement.

    here is the code and i am getting the first error on line 27:

    Code:
    #include <iostream>
    #include <ctime>
    #include <cstdlib>
    
    
    using namespace std;
    
    
    int guess;
    int i;
    int endProgram = 0;
    int win = 0;
    int j = 0;
    enum tries
    {
      five = 5,
      ten = 10,
      fifthteen = 15,
      twenty = 20
    };
    
    
    int getValue()
    {
        srand(time(NULL));
        i = rand() % 100 + 1;
    }
    int finish()
    {
        if (guess == i || j == tries)
        {
            endProgram = 1;
        }
        else if ( guess > (i + 10) && guess < (i + 50) && guess > (i - 50))
        {
            cout <<"\n\n\n\nTOO HIGH\n\n\n\n";
        }
        else if (guess < (i - 10) && guess < (i + 50) && guess > (i - 50))
        {
            cout <<"\n\n\n\nTOO LOW\n\n\n\n";
        }
        else if (guess >= (i - 10) && guess < i)
        {
            cout <<"\n\n\n\nA LITTLE TOO LOW\n\n\n\n";
        }
        else if (guess >= (i + 10) && guess > i)
        {
            cout <<"\n\n\n\nA LITTLE TOO HIGH\n\n\n\n";
        }
        else if (guess >= (i + 50))
        {
            cout <<"\n\n\n\nWAY TOO HIGH\n\n\n\n";
        }
        else if (guess <= (i - 50))
        {
            cout <<"\n\n\n\nWAY TOO LOW\n\n\n\n";
        }
    }
    
    
    int main()
    {
        char retry;
    
    
    getValue();
    cout <<"HOW MANY ATTEMPTS WOULD YOU LIKE (5, 10, 15, 20): ";
    cin >>tries;
    cout <<"\n\n\n\n";
        while (endProgram != 1)
        {
            cout <<"TAKE A GUESS: ";
            cin >>guess;
            finish();
            j++;
        }
        if (guess == i)
        {
            cout <<"CONGRATULATIONS YOU GUESSED THE NUMBER IN " <<j <<"/" <<tries <<" TRIES!";
        }
        else
        {
            cout <<"UNLUCKY, YOU FAILED TO GUESS THE NUMBER"
        }
    
    
        cout <<"\n\nPLAY AGAIN? (y/n)";
        cin >>retry;
        if (retry == 'y')
        {
            return main();
        }
    }
    Could someone please explain to me what I am doing wrong here?

    Thanks

    "tries" is the name of the type, just like "int"; it is not itself a variable.

    Tabstop has nailed the main problem.

    I'll also point out that fifteen is not spelt with an 'h'. Doesn't matter to the compiler, but does affect human comprehension.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

    By the way, you should avoid global variables. You should declare variables near first use.

    Pass appropriate arguments to those functions that need them.
