Powershell Query temp temp tables

I can run this query from SQL and it will display result against a particular server. But if I pass that server as a parameter. It returns nothing. I believe that this script may be a but to complex for  "Invoke-Sqlcmd" command. Am I right? or is there a way to run this where it produces results.

I need to run this script against a list of servers so putting it a procedure wont really work. I need to run this and out put result set to file for further processing.

Param($SQLInstance = "ServerNAME")
