I don't understand what i am doing wrong, I am trying to do an interpolated greeting code, and it won't work.

below is what i typed:

let name = "billy bob"

let greeting = "Hi there ,"

let interpolatedGreeting = "(greeting), (name)"

i followed the video to perfection i thought...but I'm missing something but i don't know what.

strings.swift 
// Enter your code below

let name = "David Hutton"

let greeting = "Hi there ,"

let interpolatedGreeting = "\(greeting), \(name)"

let interpolatedGreeting = "(greeting) (name)"

No coma after greeting in: let interpolatedGreeting = "(greeting), (name)"

Hey David,

For the first task, you've seemed to take it a bit farther and made it more complicated than what the challenge is asking for. Basically, it wants you to create a constant with your name as the value, which you've done correctly. Then it wants you to use string interpolation assigned to the constant greeting and using the constant that has your name, create the output "Hi there, David Hutton."

So, you're kind of on the right track, but you're greeting variable is not producing the right out come. You need to interpolate your name constant into the said constant.

You have to delete the constant interpolatedGreeting that you created and introduce that into the greeting variable:

// Enter your code below

let name = "David Hutton"

let greeting = "Hi there , \(name)."

Hope that makes sense. Keep coding! :dizzy:
