First of all, thanks for your time looking at my problem! Seccond, I have seen other questions like mine (for example: Uncaught Error: Bootstrap's JavaScript requires jQuery with requirejs), but they didn't awnser my question.
So, here is the <head> of my <html>
<!DOCTYPE html>

<li role="presentation"><a href="#">contact</a></li>
</ul>
</nav>

</body>
as you can see I have included jquery and the bootstrap links. but even so... I get this error message:
Uncaught Error: Bootstrap's JavaScript requires jQuery
(anonymous function) @ bootstrap.min.js:6
Do I miss something here?
