Hi, I'm using a gouge node and I know that in Value format:

1. is possible manage payload with spaces as msg.payload["what you want"].
2. is possible define decimal digits directly within the value format as {{msg.payload.whatyouwant | number: 2}}

Both work individually, but I would use them togheter. I've tried several combination but it seems not to work

I believe that @Lupin_III is trying to use  
`{{msg.payload["what you want"] | number: 2}}`  
which throws the error `"TypeError: Cannot read property '|number:2' of undefined"`.  
This does work ok  
`{{msg.payload["what you want"]}}`  
I also can't find the right syntax to make it work with `|number`

Yes Colin, exactly.  
I can't either find a solution. Maybe it's not possible.  
If so, how can I replace the spaces with "\_" inside the properties? Since they are quite a lot, I would like to avoid to rename them one by one inside a function node  
Thanks

Correct it's not really possible. either you can use the angular filters with the value {{value | number:2}} - OR - you can use a msg property. Internally they use different code paths.

Do you mean that `{{msg.payload.what_you_want |number: 2}}` should not work? It does work, where the value is in that property obviously.

This works: {{msg.payload.what\_you\_want |number: 2}} (property with no spaces)  
This doesn't work: {{msg.payload["what you want"] |number: 2}} (property with spaces)

If you want to try it before the next release of the dashboard, if you go to your `.node-red` folder and run  
`npm install node-red/node-red-dashboard`  
that will install it direct from git. Then restart node-red to start using it.  
When the next version of node-red-dashboard is released I am not sure if updating from Manage Palette will do it, if not then, again from `.node-red` folder run  
`npm remove node-red-dashboard`  
`npm install node-red-dashboard`  
and restart node-red.
