Problems when configuring Advance IIS logs with Powershell - asp.net

Question

The objectives of this script:
Create a new folder for each site
Create one log per site per day
A second script to backup/arhive scripts within a certain format
Stop all normal logging
# Ensure cmdlets are available
Import-Module WebAdministration
$Websites = (Get-Website).Name
foreach($site in $websites)
{
Stop-Website $site
}
# Disables http logging module
Set-WebConfigurationProperty -Filter system.webServer/httpLogging -PSPath
machine/webroot/apphost -Name dontlog -Value true
# Disables the default advanced logging config
Set-WebConfigurationProperty -Filter "system.webServer/advancedLogging/server
/logDefinitions/logDefinition[#baseFileName='%COMPUTERNAME%-Server']" -name
enabled -value false
# Enable Advanced Logging
Set-WebConfigurationProperty -Filter system.webServer/advancedLogging/server
-PSPath machine/webroot/apphost -Name enabled -Value true
# Move to location to store iis logs
cd C:\inetpub\Logs\Advancedlogs
# Create Folders if required
Foreach($site in $websites)
{
$FoldersPresent = Test-Path "C:\inetpub\logs\AdvancedLogs\$site"
if($FoldersPresent -eq $true)
{
Write-host "Folder exsists"
}
else
{
New-Item -ItemType directory $site
}
}
# Create hash table

Set-WebConfiguration "/system.applicationHost/Sites/Site[#name=""$AppName""]/advancedLogging" -value #{directory="$appdrive"}
}
}
# Start the websites
foreach($site in $websites)
{
Start-Website $site
}
