Hi again
BMD's are free anyway

it's just the census stuff, etc, you need to pay for.
Are you signing in under the UK version of Ancestry? It will still take the same user name and password, but may be easier to follow my instructions above.
Because not all entries of births, marriages and deaths have been transcribed and put into the search engine you may have to look at the original entries in the registers. If you are not sure of date of birth/marriage/death, you may have to look at each quarter for each approximate year until you find what you're looking for. It's time consuming work but well worth the buzz you get when you find the entry you are looking for.
The volume and page numbers refer to entries in the BMD Registers. I have never ordered Certificates from the General Register Office, but apparently you need to give them the Volume and page number so that they can find the correct certificate. I usually order Certificates from local Registry offices. Being out of the country it would be easier for you to order from the GRO.
So, in other words, sign into Ancestry Uk, try the instructions I put earlier in order to find yourself. Once you get practise at finding yourself it'll be much easier finding other peeps

. Though, if you ever find my Gt Gt Grandmother in your searches, please let me know, because I can't find her for love or money... despite searching through 4 quarters x 30 years of deaths...
Good luck.
Bex
