Don't sweat it agent87. I already apologized for being hard on people. And I wasn't picking on you per-se. I was just looking back in the thread and seeing how the tables turned. I got carried away when I saw what people were saying. I don't have an engineering background either (I actually did take an intro class that I don't really remember for 1 measly credit hour). For some reason it just seemed obvious to me from the start. I'm sure I would be wrong on many other problems, including car problems.
