On the 25th I posted a question about how the format the fields and how versatile the math functions are.
I really need to know if I can use FormCentral for what I am looking to do. Unfortunately there is no way to directly get ahold of support.
I need to know if I can format fields to sum groups of fields, and also fomat fields to do complex math equations between fields.
Please respond or let me know who I can contact.
Sorry about the delay - I just responded to your original question. Currently we don't support math functions in fillable forms but we will add your request to our product roadmap.
