While cleaning my stove I must have gotten something wet. (about 2 1/2 hour ago.) it won't start just hear the clicking and gas smell. None of the 4 turn on.. can it just be wet or is it a bigger problem if a problem how much would it cost to repair.

You have gotten the pilot light wet. You have to be careful with this. If you smell gas, then get help.

Gas smell is only when I am trying to light the stove. No other time.

Do you have electronic burner ignition? If not you somehow put the pilot light out. This needs to be relit. First air out your kitchen. Then light a match and turn on a burner and light the burner. This should light your pilot light if you don't know where it is.

I do have an electronic burner ignitor
