Questions, answered
Still wondering about Calculations? The documentation covers every setting, and we are happy to help.
What can a formula contain?
Numbers, field tags and the operators + – * / % and brackets.
Can I charge the calculated total?
Yes. In the form’s Payment Settings, set the amount to come from a field and choose the Calculation field.
Does the formula assistant need an API key?
It uses the AI service you have set up. With none, it can run a small model inside your browser instead.
Can I total rows a visitor adds?
Yes. Inside a Repeater field, a calculation can total a column across every row.
