<< you can edit the .htm file and change the range values for the slider to make it permamently go between 0 and 20 or similar.

Open the file in a text editor and find the moi:Slider element in there, the ranges are set by the values min="" mid="" and max="" or similar.

If you set them to min="0.0" mid="100.0" max="20.0" then your slider will go between 0 and 20.
