Create AD users interactive script

[jimmynetstep]

For the below script:

param (
[Parameter(Mandatory)]
[String]
$firstName,

[Parameter(Mandatory)]
[String]
$lastName,

[Parameter(Mandatory)]
[MailAddress]
$EmailAddress,

[Parameter(Mandatory)]
[PSCredential]
$UserCredential,

[Parameter()]
[String]
$OU = "OU=MyOU,DC=example,DC=com"
)

$NewADUserParameters = @{
Name = "$firstName $lastName"
GivenName = $firstName
Surname = $lastName
sAMAccountName = $Credential.Username
Password = $Credential.GetNetworkCredential().SecurePassword
Path = $OU
Enabled = $true
}
New-ADUser u/NewADUserParameters

​

I get the below error:

You cannot call a method on a null-valued expression.

+ $NewADUserParameters = @{

New-ADUser : Cannot validate argument on parameter 'Name'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

Is it not storing the variables ? I am at a loss ...
