谁帮忙看下我这个代码错误在哪？打出来之后“男”后面没有单选框
<html>
<head>
<meta http-qpuiv="Content-Type" content="text/html; charest=utf-8">
<title>单选框、复选框</title>
</head>
<body>
<form action="save.php" method="post">
<label>性别：</label>
<label>男</label>
<iuput type="radio" value="1" name="sex"/>
<label>女</label>
<input type="radio" value="2" name="sex"/>
</form>
</body>
</html>
就是这样
