I am new to project scripts and was just trying to test the simple example in the manual but I get a error when I try to run it.

Traceback (most recent call last):  
File “event:actionPerformed”, line 1, in   
AttributeError: ‘com.inductiveautomation.ignition.common.script.Scr’ object has no attribute ‘functions’

```auto
#display popup message
def popMessage(message):
    system.gui.messageBox(message)

```

you have to add the package name before your project script name.

project.js.functions.popMessage(‘Hello World’)
