Scrollview XML layout issue

Hoping this is a simple one.

I have a layout that uses a scrollview. This was fine until I wanted to put an image and textview above it then have the scrollview with my edittexts below it.

At the moment I'm getting the following errors:

01-22 20:13:32.228: E/AndroidRuntime(275): FATAL EXCEPTION: main
01-22 20:13:32.228: E/AndroidRuntime(275): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.flybase2/com.example.flybase2.addAppointment}: java.lang.RuntimeException: Binary XML file line #26: You must supply a layout_width attribute.

I have tried to change the scroll views width attribute (which i believe that error is pointing too) with no luck.

Here's my XML. Can anyone see what I'm doing wrong?:
