Thanks for your response Atsugi, and I'm sorry for wasting your time, I won't bother posting on the sub-forum as I feel I will now be wasting other peoples time too as you've given me an informative answer, I understand the car cash has nothing to do with ALS, I was thinking more other spinal issues, but ignore that, not your responsibility to comment on that. Thanks again for your time, you wont be seeing me here again hopefully.
Best regards
Nick
