I assume that you mean backslashes (\) not slashes (/) in your markup. If the form of the word in the text is different to that in the glossary (has an affix, for example), you need to mark it like \w wordform|glossary form\w*, e.g. \w ngepona liu|epona liu \w*.
If that's not the problem, maybe you're expecting a link within Paratext, but that doesn't happen. You would get a link in an app via Scripture Application Builder or an HTML version.
