You're welcome. It is very nice to receive a thankyou.
I probabaly won't follow the thread much longer as we can expect a % of small errors and an occassional bigger one as per the testimonial at another post . All data has errors. It is a matter of how many, what impact it has on our investing/trading style and what methods we can use to compare data sources for relative accuracy. At the CSI website there is a copy of an article from Futures Mag that talks about typical data errors. It is about futures data but has some relevance to all traders.
