Change AD user attributes of users in group - powershell

Question

I copied and pasted together this script that looks at all the member in a certain group, and then changes all of their company names. I would now like to expand this script to be able to ask for which attribute of the users you want to change.
Clear-Host
$GPNAME = Read-Host 'Provide the Group Name here'
#$whatwhat = Read-Host 'Which Attribute do you want to change | Put a - infront'
$attrib = Read-Host 'Give new company name here' #This should later change to "Give new info of Attribute you want to change"
$description = "-description"
$offeece = "-office"
$department = "-department"
$company = "-company"
$Userslist = Get-ADGroupMember $GPNAME
ForEach($User in $Userslist)
{
$user1 = $User.name
#Write-Host $user1
get-aduser -filter { name -eq $User1 } | set-aduser -company $attrib
}
at the end of the script i would like to change the -company with $whatwhat.
I have tried it, but no matter how, with the - or without, with ' and " around the - or the $whatwhat, it keeps on giving me this error.
Set-ADUser : A positional parameter cannot be found that accepts argument 'newly'
can anyone assist my to expand this script a little bit by giving the user options to choose from, or allowing him/her to type: company or description or office

Answer 1

you could use invoke-expression cmdlet
$cmd="get-aduser -filter { name -eq $User1 } | set-aduser $whatwhat $attrib -whatif"
invoke-expression $cmd
test :
PS>$what=read-host "attribute to change :" attribute to change ::
company
PS>$c="set-aduser test -$what 'testcpny' -whatif"
PS>iex $c
