I agree with Naren.
Sending name of the div - "current_reading" as the :update option in the
ajax call is enough to automatically replace the contents. No need for
explicitly calling replace_html in the action.
However if you want to use replace_html in your action...
do not send <%= periodically_call_remote(:url => { :action=>
:show_current_readings
}, :frequency => 5, :update =>"current_reading")%>
:update=>"current_reading"
good luck,
Nitin.
