Trying to add background text to a label

Hi, I am trying to add a text box to a label, each label contains 2 name fields, and making the text box text Gray-3 so it will appear as a watermark on each label. I can create the text box, add the text and make it Gray-3, but when ‘sent to background’ it disappears from the label. With the text box in the foreground, then ‘sending back one’ a few times does nothing, it still sits in front of the fields on the label. Tried to bring the name fields ‘forward’, but that doesn’t work either.
Does anyone have any suggestions?
