Yes, the file fields have differents names: your-file1 and your-file2.
I have tried using options too, like
[file your-file1 filetypes: pdf|txt|jpg|jpeg|png|gif|doc|docx|ppt|zip limit:5mb]
But it doesn’t works.
The file fields have also been put into ‘File attachments’ field in the Mail tab, so that they are attached to the email:
[your-file1][your-file2]
Thanks
