I have been using a invoice database to invoice my customers for a while and
now want to update it so that the product name automatically enters based on
the product number I put in another field. Example below.

Item Number field, I type in 101 and then the field of description would
automatically enter "Candy Bar" and would automatically enter the price in
the next field.

Anybody that knows hoe I would do this I would greatly appreciate the info.
Thanks
