is there anything in the scene to reflect off the front of the text (and give you an indication it’s working)? If not, a white reflecting surface with nothing to reflect won’t appear any different than an untextured object. You can put things in to reflect or put an image or noise in the reflection or environment channel to make it look ‘reflective’. If that’s not it I’d probably have to look at the scene to get an idea of what’s going on.
