Hello again,
So after testing it out this morning, we got to see if the social media icons would show up if the form’s error message occurs. We weren’t able to pre-record, and despite doing the exact same thing to trigger the error message, we ended up getting successful form submissions.
So, to force trigger an error message, we used the script suggested from this post
And found that the share icons ended up just sitting on top of the ‘Subscribe’ button. 
Would you be able to help us a little further please?
