Sprout Forms: returning error question With Sprout Forms is it possible to return an error message if a form submission is bouncing back because unique values are expected?

For example, if I have a custom HTML form called signup I would expect it to throw back an object called signup but signup is not defined. Also tried form.getErrors() but this also returns empty.

Sample form code:

&lt;form class="form form--signup" method="post"&gt;

    {{ getCsrfInput() }}
    {% set form = craft.sproutForms.form('signup') %}

    &lt;input type="hidden" name="action" value="sproutForms/entries/saveEntry"&gt;
    &lt;input type="hidden" name="handle" value="{{ form.handle }}"&gt;
    &lt;input type="hidden" name="redirect" value="{{ craft.request.url }}#newsletter"&gt;

    &lt;input type="email" name="fields[email]" id="ft_email" placeholder="Email address" class="form__input" required&gt;
    &lt;button type="submit" class="button btn btn--box btn--send"&gt;Send &lt;/button&gt;
&lt;/form&gt;
Apologies - resolved. Case sensitivity issue with variable (signUp not signup)
