Answer 1

不是number是name
<form action ="/w/servlet/text" method = "post">
Number:<input type = "text" value ="" name ="num1"/><br>
Number:<input type = "text" value ="" name = "num2"/><br>
<input type = "radio" value = "a" name = "ss" />a
<input type = "radio" value = "b" name = "ss" />b
<input type = "radio" value = "c" name = "ss "/>c
<input type = "radio" value = "d" name = "ss" >d<br>
<input type = "submit" value = "提交"/> <br>
</form>
