dude). Anyway I edited the post above AND copied the correct version here for those into making things right. Validation is funny. Most of the time is doesn't matter if you get it wrong and it hardly ever matters if you get it right. Even so it's nice to think that some aspect of my world has been deemed "valid". I once had a CAT scan done and I saved the report because it said I had a normally shaped brain. I was proud of that report.
