我正在创建一个网站，要求用户选择科目、级别和媒介，并根据用户的选择返回资源（存储在谷歌电子表格中）。
当用户打开网站时，欢迎他们的是一个主页和一个开始的链接。点击链接后，就会进入SubjectPage，提示用户从下拉菜单中选择主题。提交选科后，会进入LevelPage，要求用户选择专业水平。提交级别选择后，会进入最后一个问题，要求用户选择自己喜欢的资源媒介。最后，用户会被带到 "结果页"，在这里他们会得到一个资源列表。
到目前为止，我已经设置了我的页面，并将我的项目连接到我正在使用的谷歌电子表格。但是，我很难想出如何在页面之间携带用户的选择，并使用用户的三个选择在ResultsPage上显示信息。下面，我已经包含了截图和代码，可能会有所帮助。请随时向我进一步说明或更多截图。如有任何指导或建议，将非常感谢!
