Hi, have a look at the answers you got to this question on 9th July 2017, Derek.

That was a long time ago, my memory fails me a lot:o(( but I’ll try and find it if I can as I don’t remember asking this question before?
How do I find my 2017 answers?
Oh! It’s ok I found out how to find 2017 answers LOL, funny, I don’t remember asking before, these senior moments are a nuisance:o((

Hi, I get senior moments as well, I just happened to remember you asking this before, so I looked back through your questions, saves typing all the info again, no worries, Derek.

Ha! Ha! Derekm xx

I have been in touch with the RHS with my question but I give up as this was the reply......
