I have a table with 2 fields. Field A contains a text value and fiel B contains a number value.
I want the user to be able to select a number in field B from a value list which depends on the value of field A.
For example if field A contains "Normal", I want the user to be presented with the value list ( 0, 1, 2) in field B.
If field A contains "Extra", I want the value list of field B to be (5, 10, 15).
How can I do that ?
