I'm so sorry, I'm trying to put a link up, but to no avail - please excuse my computer illiteracy (set to Html, press link -paste - press link again?) Please help...
@David Matthew - many thanks (after all that, I hope it was worth it - kind of like when someone builds up a 'hilarious' joke and it's shite after all!!)
@ian holloway - cheers for the lesson. Must. Try. Harder.
