How come I keep geting the errors when I use the simple shooter sample?

Theres a problem with this code:

GameplayScreen.cpp

`// Create a sphere primitive to represent the player.`
`    // The sphere will be used to handle collisions and constrain the player in the world.`

`    // It is not rendered so it is not added to the list of render objects.`

`    // It is added to the object list so it will be included in intersection calculations.`

`    m_player = ref new Player(XMFLOAT3(0.0f, -1.3f, 4.0f), 0.2f);`

`    m_objects.push_back(m_player);`

`    m_player->Active(true);`

`    m_camera = ref new Camera;`

`    m_camera->SetProjParams(XM_PI / 2, 1.0f, 0.01f, 100.0f);`

`    m_camera->SetViewParams(`

`        XMFLOAT3 m_player->Position(),            // Eye point in world coordinates.`

`        XMFLOAT3(0.0f, 0.7f, 0.0f),     // Look at point in world coordinates.`

`        XMFLOAT3(0.0f, 1.0f, 0.0f)      // The Up vector for the camera.`


```Then i keep geting these errors
