Thanks, Nick and Gary. You are absolutely right. I found 'error' is being defined in a 3rd-party framework I'm using.
Then there is the question of how to work around this, so I can use the NSString class method. If you can suggest a solution I would be grateful. On Sat, Oct 27, 2012 at 7:41 PM, Gary L.
