Try using a lighter, the type used for grills. Since you can smell gas, the gas valve is working but the egnitter that gives the spark to ignite the gas is apparently not working.
Usually is it not the igniter but the controller that controls the igniter. If using the lighter as suggested, and it lites, you probably will have to replace the igniter controller for the range
