if statement - Button Click List to PopAsync

Question

I am working to go from the index count to a new window using popasync. In the code below the "If" portion works but the "else if" portion keeps braking because the count goes into the negative. How to I stop it from counting and set it to new page?

async void OnButtonClicked1(object sender, EventArgs e)
    {
        ndx--;

        if (ndx < DaggerGuard.Count)
        {
            BindingContext = DaggerGuard[ndx];
        }
        else if (ndx < 0)
        { 
            await Navigation.PopAsync(); 
        }
    }
