I have a simple script used to ping a device:

I’m calling the script from an expression tag:  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/f/0f75d775364f0ef9f044d5851d42016b3e1eb5d6.png)

The problem is the runScript does not send the arguments. Only the defaut value is used.

If I remove the default value, the tag goes in error (config error)  
If I pass an invalid IP address in the runScript call, the default value is used.

What am I missing?

`runScript("IP_Monitor.checkPing", 0, "10.161.5.5")`  
If you’re using the ‘newer’ form of `runScript` where you pass arguments separately, the first argument should just be a reference to the function to call itself. The ‘legacy’ syntax was to embed your parameters directly in the first argument, which is unwieldy.

Remove the parens from your function reference in the runScript call. I don’t know why our documentation is wrong.

It's not anymore 😅

@vrautomation I apologize for any confusion the examples in the docs played here.
