I am creating a form in InDesign CC and exporting as an interactive PDF. I want to make some of the fields calculate a sum. When I select Value Sum and click on the Pick Fields, I am able to select the fields I want to include in the sum, but when I select okay, they do not appear in the window and the field does not calculate. I was reading about some bug/issues in 2015, but did not see any resolution. Does anyone have any suggestions. I tried restarting. Uninstalling and reinstalling and this did not fix it.
Let me also say that I was trying to use the add java script in the custom field under Format and I am having the same problem where my window does not display the content after Selecting Edit and entering the information in the window.
One of the problems with the built in Sum function is that the field names cannot contain spaces or punctuation. This could be the issue. But there is a much more problematic bug with disappearing calculations. I've had this problem a few times and it usually goes away if you add a calculation to another Field, then click onto the first field that had the issue.
Oh my god, thank you. Had the same problem as OP. Removing spaces in field names fixed my issue.
My co-worker had a 7 page document that was not working. Made in CC InDesign 2021 with interactive text, signature, and checkboxes. The last step was to calculate fields in Acrobat but there was nothing to pick from the field box.
I found out that the name on a check box was the issue. There were three periods in a row. Once that was removed I was able to see the fields to calculate in Acrobat. Funny how something like that could break it.
Don't make any interactive element names with ...
I'm sure other names would cause an issue. Simple is best!
I tried what some of the users had mentioned... I made sure I didnt have any spaces in the field names. I also quit Acrobat and started up again and then it worked.
