radiobuttons, for a simple question like this. Basically:
is it a yes or no - use a checkbox (checked=yes)
is it two options - use radiobuttons

Could be tricky and depends on your data layout.
(a) you have an auto-increment ID value, then
select * from mytable where id = (select max(id) from mytable)
(b) you have a timestamp field, then
select * from mytable where dt_entry = (select max(dt_entry) from mytable)
Note that the timestamp solution could easily produce duplicates while the
auto-increments do not.
