hi Kevin,
you're welcome!
In the form BeforeUpdate event, you can validate values (for instance, maybe a value needs to be between 0 and 100, or a date needs to be before or after today), update tracking fields such as when the record was changed, undo changes, and/or cancel the update till things are okay.
The form AfterUpdate event happens after the changed record is saved. This is where you would calculate dependent values in other places ... although storing calculated values is generally a bad idea. You can also refresh and requery other forms that might be open.
Forms and Controls both have BeforeUpdate and AfterUpdate events. The principle is the same but they are different.
have an awesome day,
crystal
