Unable to print inner XML values using PowerShell - powershell

Question

I am trying to retrieve data from a SOAP web service using PowerShell. I am having issues retrieving values from the inner XML. The code is listed below.
In the [XML]$body2 variable if I pass the $queryid variable then the values in the else condition of the Response function does not print. I debugged the code and $queryid is getting the correct value. If I remove $queryid and replace it with a number then the values print fine.
Edit: The $queryid should be set to a number which I then want to use in $body2.
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$id1 = "1"
$id2 = "2"
$global:queryid = ""
$array = #()
function Main() {
$uri = "https://mywebsite/CatalogTasks.asmx?WSDL"
[XML]$body = #"
