Can't select everything in edit mode? I still can't select everything from my model when I go into edit mode. There is a red line all around one piece of my model when the other is selected. I have one modifier on the top part, if it changes anything. Here's a screengrab if it helps identifying the problem.

Thanks.
The orange lines say: this is an other object.
Select the upper object in object mode and see if I am right.
