Hello Alan,
many thanks for your response. Well, I am following the whole discussion from the very start and for my taste it is too superficial - don't know whether this is the right wording. Please get me right. We need some kind of implementation specification or a sample way on how to implement stuff. At some point I honestly lost track, thus I was asking for a summary so in the end the result is what we want. If it is clear to everyone what shall be done it should not be kind of a big deal to quickly sum it up which I/we would highly appreciate.
Many thanks Eric
