当我运行当前的 XHTML 页面时，出现以下错误：
Retrieved_Data <?xml version="1.0" ?><exception><path>/db/apps/HTML_Student/SVG_Bezier_Curve.xq</path><message>exerr:ERROR org.exist.xquery.XPathException: err:XPST0003 expecting "return", found ';' [at line 4, column 79]</message></exception>这是我的 XHTML 代码：

我很想添加我的 XQuery 代码，但这个框不允许我添加。 我有我的代码的照片，但您不让我在不复制和粘贴代码的情况下发布照片。 当此框不允许我向您提供代码时，我如何向您提供代码？
您需要用分号终止声明，即 try
declare default element namespace "http://www.TedTheSpeedlearner.com";
declare option exist:serialize "method=text media-type=text/plain";
