Moving around question

can someone one help me with this question as I don’t knnow how to complete it.

I’m on part about moving around and it says wheelchairs don’t count as aids, but there is no box to tic to say I cannot stand or move at all.

I have Spinabifida and paralysed from waste down and cannot walk, let alone stand. So how do they expect people like me to answer that question?

Yet when I read the guide book, it mentions wheelchairs 🤔
