The variable debugger doesn’t work when the variable that needs to be viewed is inside a component. There are two relatively easy ways to deal with this.

1. Use a ‘Speak’ response at an appropriate point to speak the value of the variable. Deactivate this response when you no longer need it and then you can reactivate it later if needed again.
2. Create a text object in the component and use a ‘Detect’ trigger to set the text value of that object. This is easier to see, but requires a bit more work to set it up – and it messes with the visual design.

With the speak method it is very easy to switch to tracking a different variable. And if you are not using Speak responses elsewhere they are also very easy to find.
