There is no code in your documents as docx format does not support code.

You can use the content control exit event to perform calculations, something like the attached, but you need to name at least the relevant fields (and better still all of them) and you need to have a date value that you can add to. Your Date of Manufacture field shows only the year. You cannot add months to a year. So in the attached I have added a last examination field for the purpose of demonstration.

The code adds six months of a year to the value of that date (or nothing if the field is showing the prompt).
