script to create new AD user fails - powershell

Question

I would like to atomate the user account creation with a CSV file.
I have done some tests but it stills fails.
# Import active directory module for running AD cmdlets
Import-Module activedirectory
$log = "log.txt"
#Store the data from ADUsers.csv in the $ADUsers variable
$ADUsers = Import-csv C:\Scripts\newusers.csv -Delimiter ";"
#Loop through each row containing user details in the CSV file
foreach ($User in $ADUsers)
{
#Read user data from each field in each row and assign the data to a variable as below
$Username = $User.username
$Password = $User.password
$Firstname = $User.firstname
$Lastname = $User.lastname
$OU = $User.ou #This field refers to the OU the user account is to be created in
# $email = $User.email
# $streetaddress = $User.streetaddress
$city = $User.city
# $zipcode = $User.zipcode
$state = $User.state
# $country = $User.country
# $telephone = $User.telephone
$jobtitle = $User.jobtitle
$company = $User.company
$department = $User.department
$Password = $User.password
echo = $Firstname
#Check to see if the user already exists in AD
if (Get-ADUser -F {SamAccountName -eq '$Username'})
{
#If user does exist, give a warning
Write-Warning "A user account with username $Username already exist in Active Directory."
}
else
{
#User does not exist then proceed to create the new user account
#Account will be created in the OU provided by the $OU variable read from the CSV file
New-ADUser `
-SamAccountName $Username `
-UserPrincipalName "$Username#axpenet.local" `
-Name "$Firstname $Lastname" `
-GivenName $Firstname `
-Surname $Lastname `
-Enabled $True `
-DisplayName "$Lastname, $Firstname" `
-Path $OU `
-City $city `
-Company $company `
-State $state `
# -StreetAddress $streetaddress `
# -OfficePhone $telephone `
# -EmailAddress $email `
-Title $jobtitle `
-Department $department `
-AccountPassword (convertto-securestring $Password -AsPlainText -Force) -ChangePasswordAtLogon $True
}
}
If i then run the script I get the following errors
New-ADUser : No se puede validar el argumento del parámetro 'Path'. El argumento es null o está vacío. Proporcione un argumento que no sea null o que no
esté vacío e intente ejecutar el comando de nuevo.

So I think that the New-ADUser command is not picking up the variables values from above.
How can I do to for example set a breakpoint somewhere to see the value of a variable on a specific point of the script?
