I have a repeating section on an order form, beneath this I have a total field as a calculated value. This is here to calculate the sum of the order totals in the repeating section. Using sum(Total) in the calculated field works perfectly until the value goes over 1000. When this happens the value sits at 0.
I have attached an image of what is happening
I'm going to guess its the comma "," in the numeric value that is interfering. It might be trying to treat that value as a String which would cause the sum to fail. See if removing that would fix the issue.
