What you want is to get the value when the slider has stop, not during the slide. From my experience, the slide event will get you the previous position of the slider. Stop will give you the value of the slider where the user move it to.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
