Thanks for the response, I'll have to play with it more, as I'm
obviously misunderstanding the error that I'm getting.
I didn't include the part of the script that did the math, as it
wasn't important to my base question.
I was getting TypeError: "sequence index must be integer", so I
thought the L was making python see it as a string.
Thanks for the insight
