I think over the years we have all found ourselves lacking the required knowlege at one time or another. That's why a website like this works so well is because so many of us have such vast hands on been there done that which can be handed along to help others. I stand in awe from some of the advice I've gotten here. Knowledge well and dearly learned and generously dispensed.Sorry if my post was unhelpful. I’m so used to screwing things up that I’ve learned to salvage projects in ways that were far from my original intention. Obviously the advice of others in this thread is much more useful. Glad the OP got the help he needed and that we all learned something, including that I'm an idiot.
No worries. You tried to help which is great! We ever learn from our mistakes too.
