A value list displays a list of options that you specify.
Create a value list by selecting Lookup Wizard for the field's Data Type.
Select a source for the lookup field's values.
Enter the options you want to see in the value list.
For example, if you ship a product using three different courier services, you could create a value list that displays the three courier services, such as AirBorne, FedEx, and UPS.
Although it's possible to change the options displayed in a value list, doing so is a rather cumbersome process. For that reason, you should only use for values that will not change very often. If you want to display a lot of options, such as a list of state abbreviations or values that may change frequently, you should create a table to store those values and then display them with a lookup list instead. It's a lot easier to change values in a table than it is to change options in a value list.
This lesson will show you how to create a value list that contains several static options.

If you want to add a lot of options (ten or more) to your value list or if the values in the list will change, consider creating a table to store the values and display them with a lookup list instead. Adding the initial options to a value list is easy, but adding, changing, or deleting these values can be a burden.
You've finished creating the value list!
Complete the Lookup Wizard by clicking Finish.
