I am having a problem with formulas adding extra quotes, Why is this happening?

I have a formula field that outputs a a js code for my website. I am using the html values for the quotes so it doesn't mess with the formula itself which generally works fine. The formula is as follows: 

The problem is that the output includes a second " at the end of the script url. If I remove the html code for the quote, it displays no quote, so its either 2 quotes or zero, neither of which works: 

<script src="https://www.cognitoforms.com/f/seamless.js"" data-key="mwEbRdNaJka44LUyoX8j-g" data-form="24"></script> 

Any idea why it's happening ?
