Ok thanks. Should I have posted in the ASP.NET forum?

However I am still confused at what the 73 means?

I get that CU.Centreid is the centre I am looking for but what is the relevance of 73?

Sorry if these questions seem silly but I am trying hard to understand everything and you both have been a big help so far.

The number is just an example. Is the Id of the centre you are looking for. It's just an example. You should supply the correct number when doing the query.

Yes, sorry...I should have said what parts of my example query were just arbitrary values for demo purposes. Apologies.

Cheers anyway though, i'm not complaining you helped me out alot.
