Switch-case issue

input it outputs whats under deafult:

Application should open different websites, websites that will open will depend on code that user inputs. And when I enter valid code it outputs "Code not valid. Contact @thataccount on instagram for a new one." and outputs same text if I user inputs invalid code (which is good).

here is code.

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    UnicodeString code, key;
    int br;

    Edit1->Text = code;

    if (code=="C577F") br=1;
    if (code=="A9967") br=2;
    if (code=="G02C1") br=3;
    if (code=="TB4FA") br=4;
    if (code=="U3E4B") br=5;
    if (code=="KR11V") br=6;
    if (code=="DFF9D") br=7;
    if (code=="L738D") br=8;
    if (code=="AA46C") br=9;
    if (code=="EC6E7") br=10;
    if (code=="T7BCE") br=11;
    if (code=="JT429") br=12;
    if (code=="R5F2C") br=13;
    if (code=="O582B") br=14;
    if (code=="A1FB4") br=15;

    switch(br)
    {
        case 1:
            key="1";
            WebBrowser1->URL = 
            break;
        case 2:
            key="2";
            WebBrowser1->URL = 
            break;
        case 3:

            WebBrowser1->URL =

        case 4:

            WebBrowser1->URL =

            break;
        case 10:

        default:
