go - no new variables on left side of :=

Question

What's happening here?

package main

import "fmt"

func main() {

    myArray  :=[...]int{12,14,26}  ;     
    fmt.Println(myArray)

    myArray  :=[...]int{11,12,14} //error pointing on this line 

    fmt.Println(myArray) ;

}

It throws an error that says

no new variables on left side of :=

What I was doing was re-assigning values to an already declared variable.
