Select Fields for Calculation list empty

[Guest]

Hello,

I am using Adobe Acrobat X Pro.  I have a rather large .pdf file that I have been working on.  In Text Field Properties > Calculate, I am selecting Value is the (sum (+)) and then selecting Pick.  The field Selection list no longer contains any available fields 

 

Nothing has changed for any of the fields.  I've tried closing out of Adobe without saving but nothing seems to get it back.  All of the previous fields I have set still work correctly however I am not able to make any selections for the fields that have yet to be updated.  Please help.

Thanks,

Acrobat X is quite old and outdated. Make sure you install all available updates for it.

You should be running version 10.1.16. The updates are available here: ftp://ftp.adobe.com/pub/adobe/acrobat/win/10.x/

Unfortunately this is a corporate version and I do not have administrative rights to install the updates.  Is there anything that can be done to recover the Field Selection list?

Not that I´m aware of.

It's an old known bug.

You should ask your IT to update your Acrobat X version.

You can use Javascript for the calculation.
