Swift3 compilation error

import Foundation

func stdWeight(hegihtCm height:Double, #bmi:Double) - > Double {
    return power(height/100.0,2)*bmi
}
let height = 180.0
let w1 = stdWeight (hegihtCm:height, bmi:22.0)
print("The standard weight for a person who is \(height)cm is \(w1)kg.")

When you try to publish the external and internal arguments with the same name,
Expected parameter name followed by ':'
at #bmi in line 3 There is an error.
I am writing to ask you a question because I did not know how to solve the problem after searching.
If you know this compilation error, please let me know.
