Is it possible to pass a multi line PowerShell code block to the Invoke-Command ScriptBlock option?

Question

Hello,
In my code I am trying to start a windows service on an Azure VM via Azure Automation.  My code fragment is:
$vm = Get-AzureVM -Name $VMName -ServiceName $VMServiceName
$uri = Get-AzureWinRMUri -ServiceName $vm.ServiceName -Name $vm.Name
# Run a command on the Azure VM
$PSCommandResult = InlineScript {
$options = New-PSSessionOption -SkipCACheck
$output = Invoke-Command -ConnectionUri $Using:uri `
-Credential $Using:Credential `
-SessionOption $options `
-ScriptBlock { stop-service -DisplayName <ServiceName> -Force }
My issue is: Is it possible to pass in a multiple line PS block as the ScriptBlock option?
After looking around online, there appeared to be two options:
$psblock = {
line1
line2
line3
Or
$PSCommand = @"
Line1
Line2
Line3
But I have not been able to get either of these to work. (I was trying to end up with something like below)
$output = Invoke-Command -ConnectionUri $Using:uri `
-Credential $Using:Credential `
-SessionOption $options `
-ScriptBlock { $psCommand }
Can someone offer a suggestion? Putting a few lines of PS code directly into the ScriptBlock parameter does work but it looks ugly!
Thanks!

Thanks for getting back to me!
I have tried as you suggested but when I attempt to publish the runbook I get this error:
Runbook definition is invalid. Cannot store the results of this type of expression into a variable. Only the results of commands, pipelines, constant expressions, foreach statements, parallel and sequence statements can be stored in variables.
 However if I just cut and paste the same code inside the ScriptBlock { CODE HERE } it works.
Perhaps I am breaking the rule as listed above in bold? Would variable declarations in the code block not be allowed?
