Powershell - "Invalid assignment expression." error - powershell

Question

I've got a couple things that i'm working on. One of them is sort of an import/export thing i found on here. but i'm getting the following error
PS C:\Users\joeblogs> C:\Users\joeblogs\Scripts\Copy user data.ps1 Invalid assignment expression. The left hand side of an assignment
operator needs to be something that can be assigned to like a variable
or a property. At C:\Users\delpillay\Documents\Scripts\Copy user
data.ps1:16 char:12
+ $username = <<<< gc env:userame
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : InvalidLeftHandSide
I don't know where to start and i'm not sure what to try...
Below is the code:

Few observations:
You are not commenting the Favourites and My Documents. If you want to use them then use comma separated directly.
Use this:
$destination = "E:\Users\%username%\Backup"
$folder = "Desktop","Favorites","My Documents"
#"Downloads",
#"Favorites",
#"My Documents",
#"Music",
#"Pictures",
#"Videos",
#"AppData\Local\Mozilla",
#"AppData\Local\Google",
#"AppData\Roaming\Mozilla"
You have missed the n in username:
$username = gc env:username
Donot use gc env:username. Instead directly access them like this below: Completely reframed:
$destination = "E:\Users\%username%\Backup"
$folder = "Desktop","Favorites","My Documents"
#"Downloads",
#"Favorites",
#"My Documents",
#"Music",
#"Pictures",
#"Videos",
#"AppData\Local\Mozilla",
#"AppData\Local\Google",
#"AppData\Roaming\Mozilla"

$username = $env:username
$userprofile = $env:userprofile
##$appData = gc env:localAPPDATA
These are the major things that have been fixed. Hope it helps you.
