I've put one set of figures in the wrong boxes (looks like £1000 instead of £100). I can't see how to correct this - I'm sure I've seen instructions in the past. Can I just cross it through and rewrite? I'd prefer to send in the paper form rather than do it online.
Thanks Buenchico. I'll do that. It's just the security thing - data protection. I don't see why potential hackers should see the details of my meagre income. Also I see that I may have to wait several days before getting an authorisation code, and I was hoping to have it out of the way tomorrow. But I'll think about it.
