All indications, ie the design of the green price slider indicates it will slide. It does not. It drives me nuts.
I have never been on any site, no matter what kind, where the slider doesn't actually slide. Your slider jumps. Why have a slider? I have to sit there pressing the thing over and over to get to where I want to be. What happened to the commonly known fact that things should just be 'a click away'?
Make the slider slide. It can't be that difficult because everyone else does it.
Are you referring to this rate calculator? I checked and it does slide normally for me. If you want to input more precise numbers with cents, you may put it directly into the field.
