The same as anything else, eg
if @my_array contains [0,1,2]
<%= link_to 'Compare', :controller => 'compare', :action =>
'do_compare', :ids => @my_array %>

If the values you want to pass come from fields then it just a matter
of setting up the fields correctly. Google should be able to sort you
out, I always have to look it up.

If you are only comparing two records then just pass the ids as two params.
