Thanks Raze, finally got it!
I wasn't including the address within the brackets (don't ask what I was putting there <img src="/ubbthreads/images/graemlins/ouch.gif" alt="" /> <img src="/ubbthreads/images/graemlins/shame.gif" alt="" /> ).

And apologies to Kiya - you explained it very well - its just that I didn't read it right! I guess sometimes I just have to be hit - several times - for anything to sink in!! <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" /> <img src="/ubbthreads/images/graemlins/silly.gif" alt="" /> .

Thanks again. <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
