Darren, I hope you didn’t take offence, though I suspect you did. Anyone who knows me would tell you I am not known for being subtle, but I didn’t mean there to be any bad tone simply because I didn’t see any need for one. Text on a forum often suffers due to the lack of easily discernible expressive nuances. This is just one of those cases I think. If you read your first reply to me, that could easily fall into the same category though obviously not meant to. It was good of you to offer to help
