Powershell Workflow: Using if/else statement? - powershell

Question

I am trying to use a workflow in order to make a script run faster by running a ping on several machines in parallel. Where I am getting stuck is trying to use my if/else statement within the workflow and adding log entries based on the results of the ping. Right now, it is not writing anything to the logs based on the ping results. Any assistance would be greatly appreciated. I am open to suggestions for different methods to do this, as long as they do not involve using a module. I want to stick with just Powershell code (I do not have permissions to install modules on the server where this would be running). Thank you! Here is my current code:
