Hello @civilvicky
Please, disable the dynamic evaluation of the equations, and then activate this feature by coding after rendering the form:
1. Untick the “Dynamically evaluate the equations associated with the calculated fields” checkbox in the “Form Settings” tab (https://resources.developers4web.com/cff/images/documentation/form-settings-tab.png).
2. Insert an “HTML Content” field in the form, and enter the following piece of code as its content:
<script>
fbuilderjQuery(document).one('showHideDepEvent', function(){
ENABLEEQUATIONS();
});
</script>
Best regards.
