This is my first time of doing this crossword. JimJools suggested it to me. Can someone please tell me if 37d is RAMPTON? If that is correct then if seem to have gone wrong with 45 and 47a.
Also what do I do with the squares that didn't have clues and now are filled with letters?
Sorry to sound so dumb but this is all new ot this Canuk.
Thanks for help.

Rampton is correct
45 is Acanthaceae
47 is Endogen
The theme of the crossword is a drink !
Type the letters you have in the unclued lights into http://www.onelook.com/
The yellow squares spell out a word to do with drink.
Hope this helps.
