    tarantula,
    What I meant is that I answered eswearg question in another thread but the problem was not uncovered as eswearg never posted back to my questions.

    You can start a new thread or add to this one if you are hvaing a similar problem, I would ask that you post all pertinant system and code snippet information though when you ask.
