How Can I Remove CanTouch only for one player in a script?

The title says most of it, how can I remove the CanTouch value in a script if the player has a Value called Owner1 assigned to their name?

This doesn't work:

if Owner1.Value == player.Name then
        -- I'm doing game.Workspace.[Insert Part Here].CanTouch = false, but it's still touching
    end
