When something is not working, start here rather than hunting through the calculator guides. Error messages lists the errors Calcs.com shows you and what each one actually means. Calculation not behaving is for the harder case where nothing errors but the numbers are not what you expect. Display and performance covers zoom, layout, slow loading and browser oddities. If none of it helps, the support pages tell you how to ask for a new calculator, request a feature, request a custom section, and, most usefully, exactly what to send us so we can answer on the first reply instead of the third.
