I was hoping to use the JS incase it gave me more flexibility. The last code Ive been trying is yours.
<iframe src="https://player.twitch.tv/?channel=monstercat&parent=carlos-trevino-dxzy.squarespace.com&parent=djpromote.com&parent=www.carlos-trevino-dxzy.squarespace.com&parent=www.djpromote.com" frameborder="0" allowfullscreen="true" scrolling="no" height="378" width="100%"></iframe>
using “monstercat” just to test a constant feed
my domain name (djpromote.com) is pointing to the squarespace site (carlos-trevino-dxzy.squarespace.com)
all that is done via DNS settings but I forgot how its currently setup
