dreamweaver服务器行为之“登陆用户”，用户名字段和密码字段都是username

附上代码看看哪里有问题了？
<tr>
<td width="35%" height="37" valign="middle">用户名：</td>
<td width="65%" valign="middle"><form id="form1" name="form1" method="post" action="">
<label for="username"></label>
<input name="username" type="text" id="username" size="15" />
</form></td>
</tr>
<tr>
<td width="35%" height="37" valign="middle">密码：</td>
<td width="65%" valign="middle"><form id="form1" name="form1" method="post" action="">
<label for="password"></label>
<input name="password" type="text" id="password" size="15" />
</form></td> </tr>
