Unable to use pscredentials

[Copis]

Hi @bottkars

I was trying to use this module to create new powershell script for networker monitoring but when i tried to use pscredentials to connect to NW Server i found this issue.
There are no $Global:NWCredentials assignment when you use the -Credentials option in Connect-NWServer function

I only added this line into Connect-NWServer function at line 35:
else { $Global:NWCredentials = $Credentials }
