WHY ISN'T THIS WORKING! Unresolved refrence

1

fun sayHello(itemToGreet:String) {
val msg = "Hello " + itemToGreet
println(msg)
}

fun main() {
sayHello(itemToGreet:“Kotlin”)
sayHello(itemToGreet:“World”)
}

The second part where fun main where itemToGreet is written gives unresolved refrence

named arguments use = instead of : in kotlin. Also the proper way to combine strings is "Hello$itemToGreet".
Also it would be nice if you could format the code properly and don’t use caps lock in the title. That way people are far more likely to help you.

Thank you bro, but I figured it out. All I had to do was to delete itemTogreet instead of writing it. I sat an hour thinking why this doesnt work and a friend told me why. Im pretty emberrased of myself.

Lol don’t sweat it. In Kotlin (unlike Swift), parameter names are nearly always optional, and like @Wasabi375 said, you use =, and not : like Swift :slight_smile:
