Query in Active Directory with, as variable, a attribute prompted the user

Hi to all,

please... where isthe error?

1° line of my script: $args = Read-Host -Prompt "Insert "

2° line of my script: Get-ADUser -Filter 'EmailAddress -like "$args"' -Properties * | fl SamAccountName, EmailAddress

No error is returned but I don't get the results I expect.  Do I need to modify the syntax to accomodate a variable?
