How to change a data entry form to accept new records only?

i have a data entry form which allows modification of existing data. how do I change that to new data entry only without recreating the form?

You should be able to open the form in Design mode, and then change the properties of the form to only allow new data entry. Right-mouse button click on an empty part of your form, and choose Properties. In the dialog, there should be entry that allows you to choose the type of data entry. Select the one you want, save the form and quit design mode.

Hi, the right click thing didn’t work for me either (I use a mac?). However, there is a button in the bottom left of the form in design view that does the same thing. When you hover over it, it says ‘Form’. If you click this, it opens ‘Form Properties’, which I assume is the dialog box Alex referred to. In this dialog box I was able to change the data entry mode. Hope that helps!

I need to do this, too. However:

Right-mouse button click on an empty part of your form, and choose Properties.

There is no Properties.
What next?

Did you open your form in Design mode ?
