The File Attachment field has a property "Allow the user to browse, delete, and replace files" check box. I have 2 versions of the same File Attachment field in my form (one that is enabled for this feature and one that is disabled); however, both versions of this field allow changes. I use show/hide to display the appropriate version of the field. If the field contains a file, the options for both (when clicked) are Remove, Download, Replace, and Cancel. If the field is empty, the option is the same for both versions of the field (Click here to attach a file). Thoughts?
