Here is your issue:
$NFSiSCSIVerify = Get-NaLicense -Name multistore
if ($NFSViSCSIVerify.Licensed -eq "TRUE")
You have an extra V in your second line.
Also, I'd avoid comparing a boolean value to a string. It works, but can be confusing. I'd try something like this:
if ($NFSiSCSIVerify.Licensed )
or
if ($NFSiSCSIVerify.Licensed -eq $true )
