Question

I am trying to write a script that counts down any number a user puts in.

Write-Host "$Value1"

[int]$Value1 - [int]1

do {
$outputString = read-host
$outputString - [int]1
}

until ($outputstring=0)

$Value1 defines the number a user puts in. It seems to me that the initial value gets subtracted by 1, and after that the $outputString should take the read-host information and subtract 1 untill it reaches 0.
At this point in time the only output I get is the Write-Host “[int]$Value1 - [int]1“, and the output subtracted by 1. However it does not loop untill it reaches 0.
Any way to fix this problem ?
Greetings

How about this?

do {
    $outputString = read-host enter a number
} while ($outputstring -notmatch '^\d+$')

if($outputstring -gt 0)
{
    $outputstring..0 | ForEach-Object{
        $_
        Start-Sleep -Milliseconds 250
    }
}
