In attempting to use a script for calling a popup menu found in knowledgebase article “Working with Power Table Extension Functions”, I get an error in the client console: "NameError: name ‘event’ is not defined ".  
The script is copied from the article. Any help would be appreciated.

Where are you putting your code? The `event` variable will only exist in an event routine, or when deliberately passed from an event routine to another function.

I copied the code into the “onPopupTrigger” extension for the power table in question

I found the [example code](https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/109/2/working-with-power-table-extension-functions#onPopupTrigger) you are referencing. Do you know which line the error is occurring from?  
Can you post either a screenshot or the code as it is indented in your system so we can take a look?

First image of code as entered in the onPopup Trigger ext. Second image is from the console when I attempt to open the pop up. The error is on the last line of code; menu.show(event)
