未解决的参考：计数错误（Kotlin 函数）

Question

I am newly learning kotlin, and I am playing in the Playground that kotlin created. As I was following the demo practice, I got these errors. "Unresolved reference: count" "Unresolved reference: count"
I don't understand why because I exactly mimicked the demo that is in the Example on the website.

fun generateAnswerMachine(countThreshold: Int): String {
val answerMachine = if (count < countThreshold) {
    "I have the answer."
} else {
    "The andswer eludes me"
}

return answerMachine 
}

val answerString = generateAnswerMachine(42)

Also,

fun generateAnswerString(countThreshold: Int): String = if (count > countThreshold) {
    "I have the answer"
} else {
    "The answer eludes me"
}

Answer 1

You gotta define count before using it in your function, like var count =...
