<p>I just want four different places to enter numbers between 1-8, not accepting any letters or special characters. I just need numbers. However, when I run the code, there is no input. ｀<br /><br />Can someone help me get the input to only allow numbers from 1-8. This is what I wrote:</p><p><br /></p>
<pre class="brush:php;toolbar:false;">'
<body>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

//inputs
<p1>M:</p1><input1 id="alpoint" value="-" /></div><br>
<p2>S</p2><input2 id="alpoint" value="-" /></div><br>
<p3>El</p3><input3 id="alpoint" value="-" /></div><br>
<p4>MT/hMT</p4><input4 id="alpoint" value="-" /></div><br>
</body>
'</pre>
<p><br /></p>

First of all, an id can only be used once in an html page.
<div> <label for="input1">M:</label> <input id="alpoint1" name="input1" value="-" /> </div> <div> <label for="input2">S</label> <input id="alpoint2" name="input2" value="-" /> </div> <div> <label for="input3">El</label> <input id="alpoint3" name="input3" value="-" /> </div> <div> <label for="input4">MT/hMT</label> <input id="alpoint4" name="input4" value="-" /> </div>It should be fine now
