add limitations to ranges

[liadlivnat]

Can you please advise how can i added limitation to the slider
for example i have range slider that i don't want the user can choose value lower than 5.
i handled the left and the right parts, but can't handle the center part

but the center is not working when i get into 5 it stopped than you can pull and get to zero

this is the code i added to:

var centrer_range_left = scope[refHigh] - newValue;
var centrer_range_right = newValue - scope[refLow];

              if (newValue < 5 || newValue > 95 || newPercent >95 || newPercent < 5 || Math.abs(centrer_range_right - centrer_range_left) < 4 || Math.abs(centrer_range_right - centrer_range_left) == 0 )
              {
                return;
              }
