Interactive PDF calculation fields do not update correctly

[Carugh_XD0149]

I have created a PDF that needs to carry out several simple calculations. These calculations are partly dependent on each other, e.g. a+b=c x+y=z then c+z=Total. Now I have the problem that the fields don't always update correctly. Does anyone have a solution for this problem?

The problem is in 'Field calculation order', make sure the fields that should calculate first are on top.

To change field calculation order in old acrobat:
Select 'Prepare form' tool, click 'More' then 'Set field calculation order'.

In new Acrobat:
Select 'Prepare form' tool, click on the 3 dots (the ones where say 'fields') and select 'Set field calculation order'.
