I've got the following page layout, and am having problems with making it work correctly within IE6. This page loads and displays fine in IE7 and IE8, but not IE6.

The problems in IE6 are:

- The "Comments" TextArea doesn't always display - only the associated label is visible.
- When the window is resized smaller, the first four fields disappear, and only the associated labels are visible.
- When the window is resized smaller, the two fieldsets don't scale down in size.

This is quite an urgent problem so I would appreciate some help as soon as possible, please.

I've tried to cut the following code down as much as possible.

Many thanks,

Dan
