Problem at the time to change the color of the text

I'm creating a feature to change the color of the text for all my screens, but at the time I was testing it, this error appeared:

This is my code:
Uploading: blocks.png...
The part named cambiarColorDeFondo worked when i have been tested it, but only that worked

You have been advised about your problem in your other topic already, but you do not appear to have made any changes.

You need to make a list of components (not properties e.g. FontSize) and then set the property of the component with the anycomponent blocks

Sorry, I read again, I understand now.
The first time I read it, I didn't understand it.
