Everyone, I was able to solve this problem on my website by inserting a non-breaking space (copy paste from the wikipedia article) into it's own line at the end of the text in my textbox.
Don't ignore this step. It's important.
Then, I went over to the Custom CSS page and injected this code -->
.fe-block p:last-child a {
display: block;
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
text-decoration: none;
}
Lastly, I copied all of the text in my textbox and created a hyperlink to the page on my site where I wanted to direct users.
Clicked 'Save' and voilà.
Why Tuanphan needs everyone here to private message him their web address is beyond me...
In my opinion, SquareSpace needs to step up its UI. Little things like this need not be so complicated.
