As part of one of our forms, submitters need to be able to download a template from our intranet page. In the HTML for the hyperlink I added <base target="_blank"> in order to open the hyperlink in a new tab. 

After opening the hyperlink the Submit button now opens a new tab showing the "Thank you" message, while the original submission window stays open.(the form is being submitted, however it appears as though nothing is happening)

How can I have the hyperlink open in a new tab while maintaining  the integrity of the submit button?
