Powershell querying Sharepoint list

Question

I am struggling with a script that queries Sharepoint.

This script is supposed to query a sharepoint list, then generate an output and then patch the servers. Here is the part i am struggling with..
When i run it i get this error:

Exception calling "GetListItems" with "7" argument(s): "Exception of type 'Microsoft.SharePoint.So apServer.SoapServerException' was thrown." At C:\Scripts\AUpdate\iPatch2.ps1:472 char:33 + $list = $SiteWS.GetListItems <<<< ($ListName,$ViewGuid,$query,$null,$null,$queryOptions,$nul l) + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : DotNetMethodException

Can anyone help please?

I've had no end of issues working with List Names that have spaces in them.

[string] $ListName = 'Automated Patching' )

Clone the list and check that out first. I've wasted enough time with that issue that I always try it first. If it that is the case, you can either figure out the evil nested quoting they use for spaces or re-implement with the space-free name. (You can change the DISPLAY of the name to have a space without changing the fundamental name used when you create the list... it will still look good to the boss. ;-)

update IIRC you can try the URL quoting first 'Automated%20Patching', that often is enough.
