Hi iaqu the main thing would be to look at the function when you have parameters. They can either have one or two names for a single parameter. If there is two names for one parameter then you have an external name and a local name for the parameter. You call the external name when using the function and you use the internal name inside the function.

func getRemainder(a: Int, b: Int) -> Int {
  return a % b 
  // the return statement must have these values spaced out like so

  // you need to add an external name of value to the parameter a of type Int
 // for your second parameter b you need an external name divisor
 }

// this is how it would look like 


func getRemainder(value a: Int, divisor b: Int) - > Int {
    // value is the external name used when we call the function, a is the local name we are using below inside the function 

//for the return statement. Think of it this way the local name is going to be the value the user puts into the function when 

//we call it in this problem its type Int

//the divisor is the external name and b is the local name for the second parameter 

return a % b 
}

hope this helps
