The calculations would not work if the field is empty - is there a way around it?

Hello, we have  a long form for calculations and just realized it will not work unless every field is filled in. It would non-user friendly to ask them to put 0 in fields they don't need. Can you make a script that would allow a simple subtraction calculation with needing every field filled in? http://bigfishabc.com/baris/seller-net/

I see that you are using Masked Input widget for your input fields. A great thing with them is that you can actually set the default value so you are not asking your users to do that for you.

You can see that here: http://form.jotformpro.com/form/51166155808962

Now I have a feeling that there is something else at play here as well, not just default values, but if you can check and let us know which fields are not working properly we can take a look at them and see what could be the issue.

Perfect, that works, thank you so much!!
