I had a form that submitted data via JavaScri0pt. It "compiled" in the narrow sense that data got sent, but one of the params was not working. When I inspected the HTML for the form, I saw that I had the following:

<input type="checkbox" name=nursing_care_insurance"" value=1>

If you look closely, you'll see I had two quotation marks ending the param name and zero at the start.

Lesson

The generalizable lesson is to inspect the details of code (e.g. quotation marks etc.) more carefully as a first port of call if something fails (even if it fails in an undramatic way.)
