First of all please don't play games with the font. The
usual one is fine.

Secondly rather than calling functions using:
it is better to call it with
so you don't accidentally pass in the wrong parameters.
(The first form reuses your current parameters.)
Third I would suggest that you have a final case that
reports what the parameter was and that it was not
understood. This will help debugging when (in my experience
not if) things go sour.
Fourth in chatter you got the suggestion to call
param('page') once and put that in a variable.
That idea is a good one.
Fifth, you are using strict, good, but I think you are
using too much from CGI. Try :standard until that runs
into problems. (Or using the OO form.)
I could add more, but this is probably more than enough to
digest at one go...
