Hi Ken,
Is there anywhere I could go on your site to understand what TRIN is? If it is explained in your on-line course, then please let me know as I will be signing up for that within the next week and can learn there. What you sent out today is really helpful as the hardest part is lining up the order of importance of data signals......making sure we have them in the right order. So many thanks and much appreciated. Best wishes, K.
