Hi I have the following code but i keep getting the error :

'JsonWcfService.GetVenues' does not implement interface member 'GetVenuesByLocation(string search)'

I fairly new to C amd .Net so most of this is cut and paste to be honest.

You help would be much appreciated.

the first function works but the second one doesn't.
