$increase = $myrow["first"

It might also help to at least try to understand why you normalize. Don't
just try to follow the rules, there is some art to it as well.

Read up on database normalization. (do a search on
your favorite search engine) It will give you an
appreciation of storing related pieces of info in
different tables. Though you shouldn't need a series
of forms to access the data (most of the time) - this
has more to do with your programming logic

Hi,
I really doubt putting PHP files (or any site files) on a RAM disk will
make any performance difference; and certainly not 30-50%. When the
