booststrap dropdown list in navbar not working - asp.net

Question

I have navbar made by bootstrap, all navbar items appears after I run the project but the "dropdown list" item not work when I click on it
I have this header:
<link href="css/bootstrap.min.css" rel="stylesheet" />
<script src="js/bootstrap.min.js"></script>
<script src="js/jquery-3.2.1.min.js"></script>
<link href="css/Style.css" rel="stylesheet" /><meta name="viewport" content="width=device-width, initial-scale=1" />
And this the navbar code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="css/Style.css" rel="stylesheet" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="Default.aspx">MHM CAMM</a>
</div>
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Convert<span class="caret"></span></a>
<ul class="dropdown-menu">
<li>Currency</li>
<li>Mass Measurements</li>
</ul>
</li>
<li>About</li>
<li>Login</li>
</ul>
</div>
</nav>
When I click Convert button the dropdown list not apears
My project uses asp.net and the IDE is VS2017
How to fix this please?

Answer 1

The order of your libraries is wrong. jQuery must be incuded before boostrap:
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<nav class="navbar navbar-inverse">
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="Default.aspx">MHM CAMM</a>
</div>
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li class="dropdown"><a class="dropdown-toggle" data-toggle="dropdown" href="#">Convert<span class="caret"></span></a>
<ul class="dropdown-menu">
<li>Currency</li>
<li>Mass Measurements</li>
</ul>
</li>
<li>About</li>
<li>Login</li>
</ul>
</div>
</nav>
