Hiya, some questions:
- Have you edited the data array at line 4 in the file to include the words you want to have a tooltip? The text that is compared against is the array in element 2, they are case sensitive
- Are you using a custom ui? if your dialogue screen does not use the default renpy style 'say_dialogue' you will need to add the line `hyperlink_functions (inline_tooltip_styler, inline_tooltip_clicked, inline_tooltip_hovered)` to whatever style your dialogue screen text does use.
If this doesn't help I'd need some more details/to look at your code! (If you need further help, I'll be online later this weekend to take a look)
