Way above my skill set. But I think near the top of the code in the node you need to get the `msg.payload` and make it _visible_ for use later on. eg: `var myVale = msg.payload` Then when you want to access the incoming _value_ use `myValue` in the formula. Hope that helps. But that code is WAY above me. ---

Can you explain what you are trying to achieve ? Firstly you set a boolean in the Inject node to true - but then do not seem to do anything with it You then generate a random number in function node - and overwrite the boolean you first set What are you trying to achieve ? Craig ---

Number of issues... ```auto scope.$watch('msg.payload', function(data) { _this._data = dataTemp; }) ``` 1. `scope.$watch('msg.payload', function(data)` - this should be `scope.$watch('msg', function(data)` (see the template node built in help 2. Where does `dataTemp` come from? Your function signature is set to return `data`! ```auto google.charts.load('current', { packages: ['gauge'] }).then(function () { ``` 1. You never close the bracket of the `then` callback - the closing `}` is missing * * * Actually, I give up. Too many bits of code out of place. Question: Why not use the built in chart? Question: If you want help with google charts, where did you pull that example code from (I will attempt to fix it up from a working example) ---
