Peter,
Thanks for that, It is now working. All I need to do now is update on live server. I have a follow up question.
The Columnlist.text in 3.1.4 version i was running was changed to customise the view for collections, categories and search. We had added some custom attributes to view and removed some of the other headings. I changed them all back to default setting and it worked.
Question is can I change them back to include some custom attributes we have added and if so will this need to be done everytime I upgrade.
Is this done the same way as written in the DMX admin manual?
Regards
Peter M
