A slide ignores a trigger with variables

Thanks. I did check that the variable actually changes as I need, but the object doesn´t change. It only happens in one of five slides. What I finally tried was deleting the object and insert it again, with another name, and modify the triggers accordingly. That solved the issue. But it´s a mistery why it happened. Someone of the Articulate staff told me that "this can sometimes arise from file corruption or the way certain objects or triggers are processed, particularly if the project has undergone extensive editing over time.
