Hello,

I have searched over the forum but not find a solution:

In a template node I know how to get the value from a flow variable defined in a function node ,for example:

`Amh_orig_X={{flow."origine_X"}}`

works well, but to set a flow variable from a template node ?

The documentation says something like that: `{{flow[store].name}}`

But what value have to be `[store]` ? For example, if i wish to store the value "100" in "MyValue" is it:

`{{flow[100].MyValue}}` ? or `{{flow["100"].MyValue}}` ? What is the good syntax ?

Thanks for your help !

You don't "set" properties in the template node, only read them.  
The template node is used to format messages, not to manipulate them.
