为什么不斜纹显示表格？

Question

我正在尝试使用twill访问网站：https://cuentas.itesm.mx/IDMProv/portal/cn/GuestContainerPage/ITESMPageForgotPassword

在网站代码中，我需要在personID

中填写frmChRIndex这个字段

＆＃13;

＆＃13;

<form id="frmChRIndex" name="frmChRIndex" action="validaUsuario.htm" method="POST">
    <div class="clearFields">
	    <div class="label-info">
			Usuario (A00000000 / L00000000)(*)
		</div>
	    <div class="field-info">
			<input type="text" name="personId" id="personId" value="" maxlength="9"                       onblur="javascript:this.value=this.value.toUpperCase();">
		</div>
	</div>
</form>

＆＃13;

＆＃13;

＆＃13;

当我在斜纹上使用命令showforms时，不会出现此表单。

它返回这些表格
