How do I add formula to attached Adobe Acrobat document?

Hi

I am not a java script developer, but as this is a division you need JS to avoid dividing by zero. Have a look at this:

I assume that you want to divide the actual load by the console pressure or the difference of the actual load and console pressure by the console pressure. Either way you need to tell Acrobat about the console pressure so it can be used for calculation. For that you should put all console pressure variables into fields and make these 'Read only'. That way they cannot be edited but you can reference these for your calculation. At the moment Acrobat has these only as background text which you cannot use in a calculation.

Once you have got your formula right you then need to change the format to 'Percentage' and you should be done.

I would also recommend simplifying your field names as they are complex and you may end up with errors because of typos when you change your script. If you need to calculate the difference between console pressure  and actual load and then use the result as a dividend then you may find it easier using a field to calculate that difference first (fieldname1-fieldname2, for examle console1-actual1) and set the attribute to 'Hidden' so it is not visible but can be used for calculation.

The difference calculation formula goes into the simple annotation option.

I need the difference of the console pressure and actual load divided by the actual load and this would give the load variance %. Do I need to add another column to show the load variance?

Thank you
