I'm at a loss why this is happening.

I have a current global context "totalvalue" per this:  
 ![nr1](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/9/e/9ee28b79172f889f3613a365a79d79b0f3210280.jpeg)

I'm accessing the context in a function node per the simple example flow shown below :  
 ![nr2](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/9/a959c1085e9867006034ded716c973813279ab43.jpeg)

However this returns a null value for the global get, as the payload is always zero (per the expression "|| 0"). It never returns 46515.

Must be a rookie mistake but I'm pretty sure it looks correct. Don't know if it's relevant but this is the NR addon in home assistant.

EDIT: It looks like it fails if the context is stored in the filesystem. If it's in memory it works.How do I point the get function to the correct spot?

I'm an idiot. I need to use global.get('totalvalue','file').

Leaving this up in case some one else needs to refer to it 😃
