Hi,  
I am problem with var flow.set() and flow.get()  
example of code:

```auto
var tmp ={'start':0,'open':0,'close':0};
flow.set('X1_1',tmp);
flow.set('X2_2',tmp);

```

when I want to write in the variable with flow.set('X1\_1.open',45) , it writes in all the flows X1\_1 but also in X2\_2 which contain open with the value 45.

maybe I must not write the syntax well I am seriously stuck.

Thanks for help.

Hi,  
Thanks for reponse.

I'm used

```auto
var tmp={"open":0,"close":1};
flow.set("TEST_1",RED.util.cloneMessage(tmp));
flow.set("TEST_2",RED.util.cloneMessage(tmp));
flow.set("TEST_1.close",10);

```

It's good now.  
Thanks again.

Sylvain
