changing the function to the following will ensure that there are no duplicates of the resources link and fixing the issue above
```
Function AddResourcesLink([string]$title,[string]$url)
{
$centraladminapp = Get-SPWebApplication -IncludeCentralAdministration | ? {$_.IsAdministrationWebApplication}
$centraladminurl = $centraladminapp.Url
$centraladmin = (Get-SPSite $centraladminurl)

$item = $centraladmin.RootWeb.Lists["Resources"].Items | Where { $_.Name -eq $title }

If ($item -eq $null )
{
$item = $centraladmin.RootWeb.Lists["Resources"].Items.Add();
}
else
{
$item.Delete();
$item.Update();
$item = $centraladmin.RootWeb.Lists["Resources"].Items.Add();
}

$url = $centraladminurl + $url + ", $title";
$item["URL"] = $url;
$item.Update();
}
```
