I have a subform with a memo field in it. The subform is viewed in form view, and I cannot make the memo field expand when a new line is started. It stores the information, but the horizontal size of the field remains the same.

Hi. Here's a link to a page that talks about this for reports. I don't see why you couldn't apply it to your subform. Hope it helps.
