To insert an object into a form you should be in form design mode:
Select Object from the Insert menu.
The mouse pointer turns to a cross. Move this to where you want the object field to appear, click and drag your mouse to create a box for the object field, and release.
The "Insert Object" dialog is displayed, in which you can locate the object that is to be inserted.
Once you have inserted the object field, click on Browse to switch to browse mode.
The inserted object will be displayed in each of the forms.
