Sprite not displaying when I add a line of code that moves the main camera to another sprite

I'm in the beginning stages of writing a game and I'm having a bit of a problem. What is supposed to happen at this point is that the player sprite should fall towards the bottom of the screen with the main camera following and both the player and the camera should stop if the player collides with an obstacle. What is actually happening is that I can either have the player fall and collide with the obstacle but have the camera not follow or have the player fall and collide with an invisible obstacle and have the camera following.

I've narrowed down the problem to this code section: // Move vertically endPoint.Set(startPoint.x, startPoint.y - speed, startPoint.z); // Calculate the end point. Z never changes because this is a 2D game. X is changed via player input. transform.position = Vector3.Lerp(startPoint, endPoint, (Time.time - startTime) / duration); // Move the sprite camera.transform.position = Vector3.Lerp(cameraStartPoint, endPoint, (Time.time - startTime) / duration); // Move the camera speed = speed * rate; // Increase the speed

If I comment out the line starting with "camera" then I can see the obstacle, but the camera does not follow the player. If I do not comment it out, the camera follows the player but I cannot see the obstacle.

Any help would be greatly appreciated. Thank you!
