Why is the function argument not being passed?

Question

go

Hello. I learn the basics.
Here is the code

package main

import "fmt"



func xses(x) float64 {

       var total float64 = 0
       for i:=0; i < len(x); i++ {
       	total += x[i]
       }
     return  total / float64(len(x)) 
}

func main() {
       
    x := [5]float64{ 
       98, 
       93, 
       77, 
       82, 
       83,
     }
fmt.Println(xses(x))

}

As a result, when compiled, it gives

# command-line-arguments
./main.go:7: undefined: x
./main.go:9: undefined: x
./main.go:10: undefined: x
./main.go:12: undefined: x

Thanks in advance
