Adding Data to blank fields in a table

[Sanjo]

I have a table with 15 fields. Using a form with corresponding 15 fields, assume I key into 10 of those fields the first time I enter data for a particular customer. Some time later (days, weeks, etc) I will need to key data into 2-3 of the empty fields for that particular customer. When I try to do that it wipes out data in some of the originally entered fields. Is there some info somewhere that can tell me how to "update" and key data into empty fields in a table?

thanks for your help.

How are you entering the data? Directly into the table, or with a form? If with a form, please post the code.
