InfoPath Dev

Hi all, Hope you can give me a hand with this problem. I have an infopath 2010 form linked with an access database. In 2 fields, I have an operation that divides by zero and I get the value NAN. If I don´t fill this fields, I get errors while sending the form. What I want to do is to inicialize this 2 fields to 0,00 with the event Loading, but I don´t know which code I should use to do that. Can you please help me?. Thanks for your replies.

 Where is the division operation taking place? Is it in a rule? In code? In a default value? Can you use a condition to prevent the division from happening when the denominator is zero?

Hi, The division is in default value. It´s the result of another operations.

 Could you tell us what the specific formula is?
