We have a series of container fields on our invoice layout for pdfs for various rental needs (paperwork). Sometimes those documents are updated, and thus, the pdfs within the containers change.
My superior would like me to find a way to show the date/time when the data last changed, a timestamp.
I tried going in to Manage>Database>fields - looked at "options" for the container fields but noticed the modification option was greyed out.
I then tried to set up a second field that would "getcontainerattribute" and show the date/time of modification-- but I only get a question mark when I add a document to the container.
It's imperative that the modification date/time is not triggered by someone simply clicking/opening/saving the document to their screen. It needs to trigger only when the document is removed/added.
