第四个点错了

#include<iostream>
using namespace std;
int a,b,c,d,e;
int main(){
    cin>>a>>b>>c>>d>>e;
    int sum=a+b+c+d+e;
    if(sum<100) cout<<"Gray"<<endl;
    else if(sum<120) cout<<"Blue"<<endl;
        else if(sum<170) cout<<"Green"<<endl;
            else if(sum<220) cout<<"Orange"<<endl;
                else if(sum>=220) cout<<"Red"<<endl;
    return 0;
}
