new-VMXScsiDisk command with script doesn't work

[nimoinau]

hi,

I'm new on github and on powershell.

I am testing to make a powershell script to create a VM.
I want the user to enter the size of disk with read-host command, and then the script creates the disk with the variable.

but i have got an issue.

I do not have this problem with the size of ram.
I have tried many solutions but it does not work.

I do not know if it is a bug or if my knowledge of powershell is too bad.

thanks for help.

here is my beginner script

`#dossier de travail
#fichiers iso debian
#fichier preseed original
#script preseed creator

Write-Output "Vérification de la présence du module vmxtoolkit"
if (get-module -Name vmxtoolkit) {
Write-Output "module existe"}
else {Write-Output "module n'existe pas"
install-module vmxtoolkit -confirm :$false -force
Set-executionpolicy -executionpolicy Remotesigned -Scope Currentuser
import-module vmxtoolkit -force
}

$cpu=Read-Host "nombre de cpu désiré ?"
[int]$mem=Read-Host "quantité de mémoire désirée en Go ?"
[int]$mem=$mem1024
$disk = Read-Host "Taille du disque en Go ?"
$vmname = Read-Host "nom de la VM ?"
$diskname=$vmname + ".vmdk"
#sélection du fichier iso
Write-Output "Veuillez sélectionner le fichier ISO"
