This site had an answer but I don't really understand what I'm looking at.

Make sure that the template used to create the form contains the macros
(macro: An action or a set of actions you can use to automate tasks. Macros
are recorded in the Visual Basic for Applications programming language.) that
users need to fill in the form. You might need to add these macros to the
template.
How?
Security Use caution when you are adding macros to your form. Macros may be
designed in such a way that their use could pose a security risk. We
recommend that you use macros from trusted sources only.
On the Tools menu, click Templates and Add-Ins.
Click Organizer, and then click the Macro Project Items tab.
To copy items to or from a different template (template: A file or files
that contain the structure and tools for shaping such elements as the style
and page layout of finished files. For example, Word templates can shape a
single document, and FrontPage templates can shape an entire Web site.) or
file, click Close File to close the active document (active document: The
document in which you're working. Text you type or graphics you insert in
Microsoft Word appear in the active document. The title bar of the active
document is highlighted.) and its attached template or to close the Normal
template (Normal template: A global template that you can use for any type of
document. You can modify this template to change the default document
formatting or content.). Then click Open File, and open the template or file
you want.
Click the items you want to copy in either list, and then click Copy.
Note You can only copy whole projects from template to template, so you may
want to create a custom project that contains only the macros you want to
copy to the new template.
