I have a Form Library I am using to create Company Bills. I have a field in my Form which is used to calculate the VAT of the Bill items.
When I preview the Form it works grand but when I upload it to the Site and go to create a new Form the field which has the default value applied (ie the calculated VAT) it displays NaN (Not a Number) error.
If I submit the Form you can see for a split second that the value is then set and once I reopne the Form after submission it has the correct value displayed.
I changed the default Form opening on the Library to open in the client application and this resolved the issue but I cant keep it like this - various reasons but basically I need it to open in the browser.
Can anyone help with this issue or tell me why it's doing this?
