Henrique:

I designed something similar here:

Please note, there is NO javascript in this 
example. This is all done via php/mysql with 
html/css presenting the data.

The problems you face are not solvable using 
javascript because javascript is client-side and 
the user may have javascript turned off. What you 
want to do can be done using just server-side 
technology, namely mysql and php. As such, it's 
always available for the user regardless of what 
they think they want.

I may get an argument from this list, but it's my 
opinion that javascript should be used as an 
unobtrusive enhancement to web functionality and 
not as a foundation for it.

Cheers,
