Hello!! I have a rule to condition the calculation of a price in a form. If the Price Type = Fixed, the Total Price (composed of the sum of 3 different totals) should be calculated. It goes like this: Price Type = Fixed Set a field's value: InvoiceTotal1 and the Value is: (ScanningUserTotal1 * Scanning User Price) + (Add.DynamicTotal1 * Additional Dynamic Price) + (Add. StaticTotal1 * Additional Static Price) When I test it the totals are summing up however the InvoiceTotal1 is displayed as 0. What am I missing?

Any chance you can attach a copy of your form to a reply under the options tab? Is your rule on Price Type?
