Hi Garry

My apologies for not responding earlier, I have been super busy.

One of the issues, which Claus ironed out for me was that each sets of data were/had some irregularities.

I emailed Claus directly and after a couple of email To's & Fro's it all went reasonably well to a point where I could correct any anomalies fairly timely.

Thank again though.

Cheers
Mark.
