Hi, 

Moving the sliders clean the plot.
Does any one can show me how to fix this (PS: this piece of code is a part of a procedure whose arguments are RV and SliderRanges and I need this unusual coding to make the procedure generic ... at least I guess so)

Thanks in advance

(1/2)*2^(1/2)*exp(-(1/2)*(x-a)^2/b^2)/(Pi^(1/2)*b)
