Front right burner will not ignite

Several possibilities come to mind, if you recently cleaned the stove top, you may have jarred the burner head and unseated it. So when you turn the knob for the electronic spark to ignite the gas, the ignitor is not completing the circuit to the burner head you are trying to light.
That's predicated that it is NOT a sealed burner head- then it's immoveable or removable.
Or, the jets to the burner head could be obstructed- a light blow of air around the burner head can easily remove the obstruction.
The 3rd possibility, the ignitor to that particular burner is defective.
Light a kitchen match first, bring it close enough to the burner (but not so close that you'll burn yourself) and turn it on- if it lights, you know the burner jets are not blocked.
Turn off the stove top- WAIT FOR IT TO COOL DOWN- then try to re-seat the burner head and see if it will light using the electronic spark. You may have to try re-seating the burner head by turning it to a different position until you feel it seat into place.

I'd get a briquette lighter down in there when you turn it on and try to light it manually. If it does not light, it is a gas supply problem (bad valve or control), and time to call appliance guy. If it does light, the spark path over to the burner may just be plugged with something. If you have gas + spark, but no fire, it almost has to be that the spark can't reach the gas for some reason. That usually comes from something being plugged up.
