I didn't follow most of this, but I do know that you are
treating the value you get out of the text widgets as a scalar,
and it never is. It is *ALWAYS* a 1-element array. This could
be the cause of all your problems. :-)
Try something like this and let us know if it is still
a problem:
Widget_Control, textID, Get_Value=textValue
textValue = Float(textValue[0])
Cheers,
David
