Seeing you wish to look up a name and populate the form based on the name selected, I suggest you need a combobox. There is even a wizard for doing exactly what you want. To start, you will need a form bound to a table or query, that is a form with a Record Source.
- Add a combobox to your form
Select :
Find a record on my form based on the value I select in my combobox
Select the ID (primary key), Last and First name fields.
- Access will display an example, suggesting that you hide the Key (id) column. Accept this.
- Choose a name and finish.
There are a few other small things that could be done for neatness, but you will end up with a form that find the record you want. In addition, the combo will autocomplete if you type in a few letter.
If this is an mde, which your subsequent post seems to suggest it is, there is little you can do wuth out the original file. However, you could try opening the database while keeping the shift key held down and see if that allows you to edit. If you cannot get the original and the shift does not work, you could try rescuing the data, if it, too, is stored in this file.
