Thanks for your reply but I've already solved the problem.

Hi Bruce,Here is the link. If you can have a look it would be much appreciated.AS-OPS-FRM-0003 Fault Report-C2 Master.pdf - Google Drive Thanks.Cristina.

Do you still need help with this?

I have an expandable table in my form with add row and delete row buttons. If a row is deleted from the table using the button, it also deletes the text entered on the Document Number field on the header. What could be causing this?Thanks.
