Hi Jason, thanks for helping out.
Firstly, using PhpMyAdmin all the queries worked perfectly.
Now adding the
die(WA_Sql);
resulted in this line of text being displayed on a blank browser page
DELETE FROM `bbc_service` WHERE `serviceID`='South%20Green'
It's adding %20 in the space which is, of course, not in the database.
So that makes me realise why it's not working but how can I overcome it?
