Question about INPUTS from the "Attribute Editor"

[allocate]

So, I've attached a picture of one of the Tutorial's "attribute editor" (I forget the real name) windows, and then one of mine of the same exact object on the right.

The person in the video keeps saying to do things to the INPUT section, but as you can see, I don't have one. This is while editing a revolved surface from a CV Curve. Also, I haven't been able to edit NURBS primatives this way, and I've had to go back to the beginning and create it by editing the details before creation.

Does anybody know how I can fix this?

Thanks.

It seems like your construction history might be turned off.
It's the button on the status line, left to the render button, that looks like a paper scroll. If it has an X on it, click it once to turn on construction history.
