Hi,

I'm using a function node and want to name the "store path" of the object variable.

At the moment my Output looks like  
"element\_i"

My actual code looks like this:

But I want to have  
element\_1  
...  
element\_8

I hope anybody can help me to solve my problem.  
Thank you!

The sure fire way is to make a variable for the string value you want to use:

```auto
var elemName = "element_" + i;

```

Then use bracket notation to assign the payload to that key:

```auto
msg.payload[elemName] = {...

```

Bracket notation will interpret a variable into the actual key name and give you what you want.
