What I'm trying to say is that your list form is going to be storing an ID for the item, which is going to be different in the other list. I suggested you display it as an expression so you can get a better understanding of what may be going wrong. In general, if you put a text box bound to the same field in multiple views, whatever the current value of that field will be displayed. Here's a sample form. Save it locally, right click and select design to open in design mode.
