    Probably a really simple problem.

    Code:
      
    if(Arrowkey == ENTERKEY)
    {
           bool Check = ItemBuyBox(Itemarray[Arrowkeyplace]);
            if(Check == false)
            {
                BuyBoxClear();
            }
            else if(Check == true)
            {
                BuyItem(Itemarray[Arrowkeyplace]);
            }
    }
    No matter how i look at this i am unaware of how it always takes the first if regardless of what the function returns to check. It also takes both ifs if the second one isn't else. Im really unsure why this is happening :/
    If i just put TRUE or FALSE it works fine :/

    Code:
            else if(Arrowkey == ENTERKEY)
            {
                switch(Arrowkeyplace)
                {
                    case 0:
                    {
                        return true;
                    }
                    case 1:
                    {
                        return false;
                    }
    
                }
            }
    This is the code that returns the BuyBox function.

    If i get it to return the value to cout it outputs
    184 for both true and false :/

    Show us the code for ItemBuyBox().

    Code:

        char Arrowkey = '-';
        //Setup Question//
        BuyBoxClear();
        SetConsoleTextAttribute( GetStdHandle( STD_OUTPUT_HANDLE ), 7 );
        ReadString(Question,0,1,LeftSide+45,TopSide+18,2);

                    SetConsoleTextAttribute( GetStdHandle( STD_OUTPUT_HANDLE ), 11 );
                    ReadString(No,0,1,LeftSide+45+Itemname.size()+1+1+Yes.size()+3,TopSide+19,2);
                }
                else if(Arrowkeyplace == 1)
                {
                    SetConsoleTextAttribute( GetStdHandle( STD_OUTPUT_HANDLE ), 11 );
                    ReadString(Yes,0,1,LeftSide+45+Itemname.size()+1+1,TopSide+19,2);
                    SetConsoleTextAttribute( GetStdHandle( STD_OUTPUT_HANDLE ), 7 );
                    ReadString("/",0,1,LeftSide+45+Itemname.size()+1+1+Yes.size()+1,TopSide+19,2);
                    SetConsoleTextAttribute( GetStdHandle( STD_OUTPUT_HANDLE ), 6 );
                    ReadString(No,0,1,LeftSide+45+Itemname.size()+1+1+Yes.size()+3,TopSide+19,2);
                }
            }
        }
    }
    And it is surely contained in this and any functions that are user made out side of this are free of this error.

    Are the following variables global?
    Arrowkeyplace
    Arrowkey

    I would start by changing this...
    Code:
    if(kbhit())
    {
        Arrowkey = getch();
        if(Arrowkey == 0)
        {
            Arrowkey = getch();
        }
    }
    To this...
    Code:
    if(kbhit())
    {
        Arrowkey = getch();
        while (Arrowkey == 0)
        {
            Arrowkey = getch();
        }
    }

    No those 2 variables are not global i declared them at the beginning of the header.
    The LEFTARROW RIGHTARROW ENTERKEY are global.

    That actually makes it sound like they are global.

    I get maybe two dozen requests for help with some sort of programming or design problem every day. Most have more sense than to send me hundreds of lines of code. If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    No i meant its in the beginning of the header within both functions.

    Say what? How about you just show an example of your header file with these functions and these variables?

    Outside of your DOS world, your header file is meaningless.

    The function above shows how i init and use the variables.
