Layer masks

[Chana97]

I created a layer mask which has some text on it and I wanted to hide it behind a bottle and to disappear the parts which were covered under the bottle. And also I wanted that to be a permenant Only to that parts but not the whhole text, so if I wanted to move my text, I can move it with the full text. But it didn't work out as I wanted. Your help is highly appreciated in this. Thanks.

@Chana97 not really sure what you're asking, it would help if you posted a screenshot of the Photoshop interface with all the pertinent panels opened
