Hiya, so sorry for the late reply.
I'm little confused by your style declaration, usually styles are written as follows
style some_style_name: font "some_font.ttf" hyperlink_functions (inline_tooltip_styler, inline_tooltip_clicked, inline_tooltip_hovered)
Rewriting it in the above format may help.
If you're having trouble locating the style itself, you should be able to hover over the text in game and press "shift-i" to inspect the elements under your mouse. This should tell you the style your text is using.
Let me know more details if this doesnt work, and sorry again for the late reply!
