I have no idea if this is possible, and I have tried a few solutions I have found through here and other websites. Nothing works so far.

I'm trying to create a form and want to use Mailmerge to help show certain data/documents I have received for something. I have a column in Excel that is a yes/no answer:

IMMUNIZATIONS
Yes
No
Yes
No

So the merge field would be IMMUNIZATIONS, and I want to have the "Yes" shown as a filled checkbox and "No" as an empty checkbox.

So essentially it would be: (CHECKBOX) Immunizations

Thank you
