The picklist values I created are not showing up
If you're on Enterprise edition check to make sure they're available to the record type or if there's a field dependency set up. You can find the Record type area by going to Setup || Customize || Accounts(for example) || Record Type. Then click on the Record Type name then edit next ot the name of the picklist field that you had added values to and make sure they are selected. Field dependencies can be checked using the button at the top of the list of your custom fields.
