The user entered a value that was not a double when the call to nextDouble on line 49 was made. It's hard to make a user enter valid numbers, but for testing you should be careful to always enter a valid value.

One BIG PROBLEM in the code is the misplaced and mis-used {}s. {}s should always be used with if statements:

   if(the condition) {
      // the code to do when the condition is true goes inside the {}s
   }

There are other {}s that do not have any reason to be there. For example the { BEFORE the if statement.
