Glad I could help didymus7.
I think you will find, over time, that the deeper you get into Sonar the more robust it seems. When you described your problem I merely thought of the data structure that would be required, and missing in your previous project version, and thought that on a Save Sonar would build out the stub data structure to hold the PC...I got lucky me thinks.
BTW: Welcome to the forum, I think you will find that there are lot's of individuals on this forum who have a wealth of knowledge and experience and are quite willing to pitch in.
Best of luck.
