Can we stop necroposting for no reason, please? This topic dates back in August 2012 and the other day you bumped an intro topic dating back before the TI-Nspire existed (2006)
On the other hand, now that I see this topic title, I must remind our recent users that if they ever need help, using a descriptive title without all-caps is generally recommended, and saying it's urgent will not speed things up.
