After placing a calculation formula for 2 fields Acrobat automatically places a number in that field which I would like to remain hidden unless something has been entered into that field. So in the image below I have the quantity box being multiplied with the unit price. For all of the fields that nothing has been entered there is a $0.00, and this is what I want to get rid of. I tried the hide option in the property pane for the top extended price box but then it will not show the total for that field. I need these boxes clear so that this form can be printed and filled out or filled out and then printed. Any help would be greatly appreciated!
