What is the listener asked to do if she finds an error?

Hi, Wendy—I’m calling about the purchase orders we received for office furniture. The Accounting Department’s going to need more of everything to accommodate all their new employees. But luckily, the Human Resources Department just wants more chairs; they said everything else is OK. Before you place these orders though, be sure to check the inventory. If we’re still short, then we’ll order the necessary items. Please remember that only I, as your manager, can make changes to orders you’ve already submitted. So let me know if you spot an error that needs to be updated. Thanks.
