I am having trouble with an import user script for Active Directory. It was working before then i added Employee ID, Address and SamAccountName now I'm receving bad syntax errors can i please get some help with this.
Script:
# Create password for users
$Password = ConvertTo-SecureString "Bevchain123$" -AsPlainText -Force
# Inputing CSV file path
$CSVlocation = Read-Host -Prompt "Enter path to CSV file"
# Puttting file into a variable
$users = Import-Csv $CSVlocation
#Create for each function to grab data from CSV file
foreach ($user in $users) {
#Frist name
$FirstName = $user.'First Name'
#Last name
$LastName = $user.'Last Name'
#description
#$Description = $user.Description
#Orginisational Unit Path
$OUpath = $user.Unit
$EmployID = $user.'Personal Number'
$Address = $user.Address
$aaccount = $user.Samaccountname
# Create the Active Directory user for each line of the CSV
NEW-ADUser -Name "$FirstName $LastName" -EmployeeID "$EmployID" -SamAccountName "$aaccount" -GivenName "$FirstName" -StreetAddress "$Address" -UserPrincipalName "$FirstName.$LastName" -AccountPassword $Password -ChangePasswordAtLogon $false -Path $OUpath
# Message output to screen
Echo "user created successfully for: $FirstName in path: $OUpath"
}
