Answer 1

From the comments above:
all of the members tables show advertisementexpiry at 0
Your query tries to match anything with advertisementexpiry > 0. That means the query will never match any rows since none are greater than 0.

Answer 2

you need to break down this bit t.MemberID <> '' and t.MemberID = m.MemberID and m.advertisementexpiry > 0 and t.active = 'yes'
test each piece to debug
t.MemberID <> ''
looks like its not needed as i am pursuming every member has a id.
