Online filing P35

 Oh, woe is me! I tried to do my P35 online today. Yes, I know it's early, but I'm going away soon and I want it all done before I go.  I use Instant Sage for my own P35 and all went well until I got to the P35 front sheet.  Up popped a screen with little boxes in it, which I had to tick yes or no to.

1st problem: I use a laptop with a very small screen and the form didn't fit on it properly.  Consequently, the boxes were all over the top of each other.  I couldn't see the words and I couldn't tick in the boxes.  I tried and tried and it would not work!! Help me please.  What do I do.  I can't send it online without all the boxes filled in and I have to do it online apparently.

2nd problem: I didn't understand all the questions. Question 6 says 'Do the rules relating to services provided through an intermediary (sometimes known as IR35) apply to any work carried out by any worker listed on this return?' What does that mean, please? Question 6a, which follows on from Question 6 if answered 'yes'. I don't understand that one either.

So after doing all the work necessary to get to that last stage, I was scuppered right at the end and I still haven't sent it online.

Any help greatly appreciated.
