[support] Field labels in a view

Hi All, I am pulling my hair out over something I assume should be very straight forward. I have a few fields defined in a view like so: http://imgur.com/FiViBPf These fields are then displayed in a table, problem is the first two fields show 'PHP' as the table header and the third behaves as expected. I can't find where to set the text for the field I have looked here, but it does not let me specify the text? http://imgur.com/YAH4RtY This is what my display looks like in the end :-( http://imgur.com/w1B8w7Q Please could somebody point me in the right direction, where do I edit this text. -- Thanks Wayne
