update custom application properties with Powershell

I am so close but just missing out on the perfect solution.

I created 3 custom application properties.

and I created a script that grabs the certificate associated with a host and port number.  I need it to populate these 3 custom properties to be able to report on these within the application.

I send in 4 variables.

IP address, Port number, Node ID, and Application ID

${IP}, 443, ${Node.ID}, ${Application.ID}

The only thing is the application ID is not populating.  It is sending in literally the words typed: "${Application.ID}".

How can I make sure it passes the Application ID?  Any help is greatly appreciated!

I used this thread for variable reference https://thwack.solarwinds.com/docs/DOC-188909

Aside from the application ID, it seems like some of the variables don't work also: ${PASSWORD}, ${creds}
