hi everyone, I'm trying to create a global variable but it is registered as an object and not as a value, what can I do?  
Example I would like the output of the "file\_iniziale" variable to be the same format as the "file" variable

Dont write an object to it?

show us how you set this global variable & we will show you how to get the internal `file` value.

Please post these as code/text not images and I will show you exactly how to correct this.

(I cannot edit text in an image & and I don't feel like rewriting it everything 😉)

What are you trying to do in function 42?

Can you replace all this confusing code with this?  
`global.set("file_iniziale", msg.payload)`

Which should result in global.file\_iniziale == "change" (or whatever is in msg.payload)

sorry I'm stupid I solved the problem by removing the function of the first image  
"  
var file {}  
{  
file: msg.payload  
}  
"  
thanks for all
