Thanks for your help Gordon. The Mobility section seems really confusing and badly thought out. I want to make sure I've been accurate in his abilities, considered everything and ask for the appropriate award which is difficult given the wording. More difficult if guidelines don't hold much weight either. My son has problems going out for a wide range of reasons and I hope a tribunal will be fair in their decision. I'll definitely be focusing on criteria of reasonably, reliably etc. Thanks again fro your help
