Dear Everyone!

I have written some code, and it works, exactly how I want it to but:
I realise that I have made it both unsofisticated and a little long winded (I am sure I have some extra variables I don't really need in there somewhere!).

Could anyone here look over it for 5 mins and give me any code suggestions or advice? It's the only way we learn is if we are corrected!

Thanks!
Ellie

- Alternatively I can send through the moclup files I have been using to create the code in the first place, if that would give more context.

Code:
