In the "Text Field Properties" > "Validate" > "Use custom validate script:" I've been using the following code in AcrobatPro and it works great to show nothing if the value is 0 on a calculated field. if(event.value ==0) event.value = ""; My customer is using Nitro PDF and this will not work for him. The field shows "$ 0.00" when it should be blank. How should this be coded to show nothing in Nitro Pro if the value is 0?   Thanks Jim
