Sorry for the formatting errors, but thanks for the help correcting that.

So what I'm doing is trying to add multiple buttons to a window. I have one, and this is a second set of code below the first button. I've looked between the two, and it's the same. The only thing I can think of is maybe I've placed the brackets incorrectly. Here's the full code:

{
        case WM_CREATE: {
             
             
             CreateWindow(TEXT("BUTTON"), TEXT("Options"), 
                 WS_CHILD | WS_VISIBLE, 
                 10, 10, 80, 20,
                 hwnd, (HMENU) ID_BUTTON, NULL, NULL
             );
             
             break;    
        }
        case WM_COMMAND: {
            
            if (LOWORD(wParam) == ID_BUTTON){
                  
                  
                MessageBox(hwnd, "No Options Available", "Error", MB_ICONINFORMATION);  
                  
            }
            
            break; 
        }
    
             
       { 
             CreateWindow(TEXT("BUTTON2"), TEXT("Open"),
                 WS_CHILD | WS_VISIBLE,
                 10, 20, 80, 20,
                 hwnd, (HMENU) ID_BUTTON2, NULL, NULL
             );
             
             break;
        }
