Hi

I've designed a form in word - working well.

I would like to add a button at the end of the form, which when pressed by user will save the document in a file-name according to text in 2 of the fields.

Field 1: Surname - this is constructed in the form by using the legacy tools, text.
Field 2: Date of Birth - this is constructed in the form by using the legacy tools, text.

So the button at the bottom, once form filled by user, will save the document as:
Surname Date of Birth.docx

i.e. If Field 1 = Smith, Field 2 = 10/10/67 - file to be saved as smith101067

Is this possible?
