// My Code
let name = "jay" let greeting = "(Hi there,), (name)"
//The Errors
swift_lint.swift:6:22: error: expected ',' separator let greeting = "(Hi there,), (name)" ^ , swift_lint.swift:6:28: error: expected expression in list of expressions let greeting = "(Hi there,), (name)" ^ swift_lint.swift:6:19: error: use of unresolved identifier 'Hi' let greeting = "(Hi there,), (name)" ^ swift_lint.swift:6:22: error: use of unresolved identifier 'there' let greeting = "(Hi there,), (name)" ^
// My Code
let name = "jay"
let greeting = "\(Hi there,), \(name)"

The Hi there, did not need "/()" Interpolation string
let name = "jay"
let greeting = "Hi there, \(name)"

It is used to be able to add the value stored in a variable to a string. "Hi there," is the string and 'name' is your variable. What does this mean? You only need to interpolate the variable in your string. Understand?

2,658 PointsThank you both for your quick responses!
Being a newb, and watching the lesson a second time, I see what caused the problem: The videos in this section only show concatenation used alone and interpolation used alone. It doesn't show the usage of both simultaneously, so being that I was on the second video (interpolation), I used the interpolation method shown in that video, which was two comma-separated constants within parentheses surrounded by quotes. I thought the string literal would also need to be inside the parenthesis.
Team TreeHouse ––– For newbs (like me), throw a hint in there that we don't need to wrap the string part of the expression within parentheses when assigning strings and constants simultaneously into values for another variable or constant. That would be awesome!
