I have a layout of fixed-pixel width (960px) with a navigation bar that has five items in it. The width of the nav div is set to 100%, but its content ends up taking exactly 960px.

I'm not much of a web programmer, but I'm creating a simple web app that has a form where the user can enter a series of points (x,y,z) but I don't know how many the user is going to enter. I don't want to guess the probable maximum (100 maybe?) and put 100 fields on the form because it would look ugly. What's the easiest way to add more...

I've searched a bit, but could only find information regarding IE issue...

I have a top-level page called ReceiveItem. Within that page, I have a couple different FORMs - only one of which will be filled out and submitted (depending upon how that item is received).
