Thank you Alex

I can see I have a huge learning curve here.

No matter, I like a challenge. I have a couple of questions that will help me get a grip of the issue:

1) Can you point me to any training documentation that will help me understand concepts such as "decorator", "@ListChild" and other OO constructs. I am familiar programming in C++, so understand the principles such as inheritance, methods etc, but I am unclear how XC5 uses those constructs.

2) Do I need to create a Module to achieve what I need, or can I write suitable code and place it in the current Tab contents? I do not plan to distribute the changes.

Many thanks
