What could be causing me to get the YSOD: "Section blocks cannot be nested. Only one level of section blocks are allowed."?

Question

I can see, indeed, that the code above the section flagged as suspicious above is wrong, because the closing "}" is not yellow.

At the top of the page I have some using directives:

@using System.Configuration
@model CCRReporter.Models.TLISReportModel

@{
    ViewBag.Title = "Transaction Line Item Sales Report Criteria";
    ViewBag.PageName = ViewBag.Title;
}

...followed by a script section:

@section ScriptContent
{
    <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript" defer> </script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript" defer> </script>
    // etc.

<script type="text/javascript">
        var bSubmitting = false;
        var WantsFocus = null;
        var bFocusing = false;
        var report_parms = null;

        function SetTabOrder() {
            $.each([
                "#BeginDate",
                "#BeginTime",
                "#EndDate",
                "#EndTime",
                "#InputSite-input",
                "#cmdAddSite",
                "#InputDept-input",
                "#cmdAddDept",
                "#IncludeDepts",
                "#ExcludeDepts",
                "#UPCBeginsWith"],
            function (i, n) {
                $(n).prop("taborder", "y");
            });
        }

        // ready handler
        $(function() {
    // etc.

...this jQuery has been validated via jsfiddle/jshint.

Here is the YSOD:

I've looked over all this code multiple times, and have no idea what the problem is. Has anybody run into this before, or know of a trick for finding just where the problem lies?

Easy fix would probably be just placing your javascript in an external file and including it like the other js files. Otherwise, you'd need to escape all `}` inside the javascript somehow. i'm not familiar enough with asp.net to suggest how to do that. — Kevin B, Aug 15 '13 at 18:05
Okay, I did that, leaving only the script references and the ready handler inside the Script section, and the same problem still holds. — B. Clay Shannon-B. Crow Raven, Aug 15 '13 at 18:20
Right... but the ready handler still has a closing `}`, wouldn't that close the @section too early? — Kevin B, Aug 15 '13 at 18:28

I still couldn't find any syntactical problem with the code, but on closer inspection, the logic of the code seemed quite bizabre (combination of bizarre and macabre):

It had a submit_button click handler that called $("form").submit();

If "submit_button" really is a submit button (input type="submit") - and it is!, why would that be necessary? Not only that, but the function called from the click handler had been declared this way:

$("#form0").submit(function() {

form0? What the Hec Ramsey?!? There is no "Form0" anywhere on the page...

Once I moved the code for submitting from the Form0 handler (which, I admit, I had previously changed from selecting the phantom 'form0' to 'form') to the submit_button handler, the much-awaited and yearningly longed for yellow background returned to the section's ending "}".

Voila!

Maybe the debugger is smarter than I thought: it goes on strike not only when the code doesn't compile, but also at times, apparently, when it (the code, or, by extension, the carbon-based biped who wrote it) a candidate for the loony bin.

Alas -- I know why the caged bird sings: he was trapped maintaining the code of birdbrains who had flown the coop!

What could be causing me to get the YSOD: "Section blocks cannot be nested. Only one level of section blocks are allowed."?
