Outlook and Address Book

I recently switched from Outlook Express to Outlook (from Office XP Pro). All of my email address contacts are in my Address Book. Every time I click on the "To..." button in Outlook, and the Select Names window appears, needless to say, it is empty, yet all of my email address contacts are in my Address Book. I'm wondering how I can get all of my email address contacts into the "Select Names" area so that I can access them when I want to create and send an email. Any suggestions would be greatly appreciated and I thank you in advance.

Did you import the address book from Outlook Express to Outlook?

If not:
In Outlook
File > Import and Export
Follow steps in the Wizard.

This is how I did it: I exported my Address Book as a *.wab file. I then selected the Import and Export... while in Outlook. I chose to Import Internet Mail and Addresses. I clicked Next and chose Outlook Express 4.x, 5 and selected Import Address Book and unchecked the other boxes as I only wanted the email addresses. I clicked Next and chose the Outlook Contacts Folder for the destination of imported addresses and then chose the options that I wanted. I then clicked Finish and vwallah.... Thank you for the reply.
