未定义（类型[] DataReponse没有字段或方法）

Question

I'm trying to compile the following piece of code

    var result []DataReponse
    if result.Commenter == "teacher"{
        sender = models.CommentUser{
            Name:result.UserName,
            Email:result.UserEmail,
        }
    }else{
        sender = models.CommentUser{
            Name:result.ChildName,
            Email:result.ChildEmail,
    }

I am receiving the error result.Commenter undefined (type []DataReponse has no field or method Commenter) here is my struct

//DataReponse is the structure of the response
type DataReponse struct{
  CommentText   string              `json:"comment_text"`
  Commenter     string              `json:"commenter"`
  ChildEmail    core.NullString     `json:"child_email"`
  ChildName     core.NullString       `json:"child_name"`
  UserName      core.NullString       `json:"user_name"`
  UserEmail     core.NullString       `json:"user_email"`
}

how can i use result values ?

[]DataReponse is a slice of DataReponses, i.e., there may be more than one response (or none). You could use a for loop to run some code for each struct DataReponse returned. I would consider doing the tour. (Also, perhaps you meant DataResponse, with two "s"es, but of course that doesn't matter to Go as long as you use the same name consistently.)
