Hi Fredrik. I'm afraid that your question is a little confusing. If you could re-word it, avoiding using terms (like GroupArray:) which will only make sense in terms of your project, but mean nothing to most of the rest of us, that would help.

It's not at all clear (to me anyway) exactly what the question is that you are asking? I would suggest that you re-write your question and post it as a reply to your original.

One method I use to clarify my own questions is to try and explain the problem to a non-technical person first--your spouse, a security man, the dog:)--anyone not involved in the project would do as that forces you to word the question in terms they understand. You need to give us (at least) the input to the problem, the required output, and some form of explanation of how to get from the first to the second. This is often best done by showing us the code you have, the results it is currently producing and how this differs from what you need.

That type of question nearly always gets several answers here.

Oh, and when you post again, could you please use <code>....your program goes here....</code> tags instead of <pre>...</pre> tags. This will save the editors here some work. Thanks.
