I have a view called Company which contains

GROUP             Company
--------             -----------
HP                   Singapore, Malaysia, Thailand, Italy
MOTOROLA      Penang, Kuala Lumpur, Ipoh
Philips              Cambodia, Taiwan

When user go to another view and click to enter a new document,
Under one section :

Customer     Group  field A(editable dialog list which get the values from view Company
                                        column 1)
                   Region field B(editable dialog list to display values based on field A to let    
                                        user select which coompany to display)
                              button field C (display all companies depend on value in field A)

e.g when user select HP in field A, it should display all the companies which are Singapore, Malaysia, Thailand, Italy in field B.
when user select Philips in field A, it should display all the companies in field B.

How to I code my field B to work as the example above and the button field C to display all the companies depend on the value which user select in field A?

Do what Sjef says... in case you were also asking how to set up teh fields so they have those choices in the first place, here's how:

I will assume the first field is named GROUP and the second field is named REGION
Fields should both be Dialog List fields
Go to properties for GROUP
Go to second tab
The drop down in the "Choices" section should say "use formula for choices"
Formula should be @DBColumn(""; ""; "Company"; 1)
Go to the second tab of properties for REGION
Drop down should also say Use formula for choices
Formula should be:
queryResult := @If(!@Trim(Group)=""; @DbLookup(""; ""; "Company"; GROUP; 2); "");
@If(@IsError(queryResult); "Error - " + @Text(queryResult); queryResult)

Make sure that the Company view sorts on the group field, that the first column has group, and the second column has region.
