Assuming you assigned attachmentOne and attachmentTwo via the Inspector, you should use small 'r':

attachmentOne.renderer.enabled; // for example

That error means that your VARIABLES have not been assigned in the inspector.... and if it has.... chances are it HASNT on another object (chances are another object also has the code attached... maybe accidentally, and you just need to remove the script from that object.)
