PowerShell: Script to delete files older than X days

Question

Hi All,
I am testing a script to delete files and I have it written down in my notepad as below:
$foldername = $args[0]
$maxage =      $args[1]
gci $foldername | Where-object {($_-is [io.fileinfo]) -and ($_.lastwritetime -lt (get-date).AddDays(-$maxage) ) } |
remove-item -whatif
Question: When i try to run the script and  pass the parameters $foldername and 30 it doesn't return anything. I am expecting it to return with -Whatif
To execute the script I wrote:
.\myscipts\del.ps1  cmd2 30
cmd2 is the name of the folder in my drive and 30 is ($maxage)  number of days old.
Thank-you

Thansks jrv, looks good! One more thing I wanted to ask do you know what it means by the error:
"An Empty Pipe Element is not Allowed" I altered my script a bit but it gives me this error. and I am passing no parameters when i call the script. My Script I created is below:
$name = $args[0]
$chew = $args[1]
IF ( $args.count -lt 2)  { Write-host "Please provide 2 parameters for this to work"
                exit 1 }
GCI $name | Where-object { $_-is [io.fileinfo]  -and ($_.lastwritetime -lt (get-date).AddDays(-$chew))}
 | remove-item -whatif
Thank-you
