__NOTOC__
The <var>FormFieldNotFound</var> exception class describes an exception associated with not finding an expected field within [http://www.w3.org/TR/html401/interact/forms.html HTML form] data, say a missing "type=file" field.

To produce a <var>FormFieldNotFound</var> exception yourself, you typically use a <var class="product">SOUL</var> <var>[[Exceptions#Throwing exceptions|Throw]]</var> statement with a <var>FormFieldNotFound</var> <var>[[New (FormFieldNotFound constructor)|New]]</var> constructor. This statement must be issued from within a method, and it can only be caught by the code that calls the method. For example, the following statement throws a <var>FormFieldNotFound</var> exception:
<p class="code">throw %(FormFieldNotFound):new
</p>

For an outline of how you might use an exception in a function of your own, see this [[Get (HttpRequest function)#exception-eg|Get method example]].
