We have a list in SharePoint 2010 and several of the columns are drop-down menus. When we go to the list settings to add/update the choices, they do not appear in the form. The default choices (Enter Choice #1, etc.) appear instead.
@Christopher Sheehan It looks like your form may be an InfoPath form, not an out of the box SharePoint form. You will have to open the form in InfoPath, say "yes" to updating existing fields, then Publish the form back to SharePoint.
