Script Automation of VM in SCVMM 2012 R2 Rollup 1 - Cannot retrieve Mac Address

Question

Hi All.
I am creating a script for automation of VM
I have run into a problem, I get my vm created as it should( at least I think so) I can boot the machine and in there I see a MAC Address from the console view, I know the machine has a mac address.
I have tried to get my mac address like this, the result is blank
Get-SCVirtualNetworkAdapter-VM$VMName|SelectMACAddress
$ShowMacAddress.MACAddress
But if I go into the SCVMM Management console, and right click on my newly created machine and click refresh, my Mac Address suddenly shows up.
I have tried this link, but it does not work for me

Please help me, I am stuck
Ricco
Ps. do I need to post the rest of my script?

If you are trying to get this information immediately after the VM creation, VMM may not have the information. To my understanding, once the VM is created and the VMM get the updates while refreshing the VM, these updates will get updated.
As a workaround, you could initiate a refresh immediately after the VM creation and then query the MAC.
Refresh-VM VMName
After a successful refresh, you should be able to query the mac address.
