here is the table structure:

first table
pool id
pool name
pool question
pool votes
start date
end date

second table
answer id
pool id
answer
votes

vote once per pool

on the same page there could be several pools (depending on the start
and end date) and when voted i wanted to store pool id in a cookie -
then whei i actualy want to print a pool on the page i do this

read from db
loop
if cookie exist (with the pool id)
print pool results in a table
else
print pool in a table
end loop

that should be enough
