Help with custom CSS coding - missing '}'

Hello, 

I am trying to edit my custom css coding and out of all the videos and blogs that I have watched and read it seems like I have everything perfect but I don't because it's Squarespace isn't switching my font as I'm making the changes. I have uploaded the files and everything. Here is what I have but it tells me on the bottom in red that I'm missing '}'  and I have no idea where this is supposed to go. Any help would greatly be appreciated as I'm about ready to give up.... I copied the whole thing just incase I were to have missed something. 

//Bizantheum Font//

@font-face {
  font-family:'Bizantheum' ;
    src: url (' https://static1.squarespace.com/static/6520617e9dd5526c34876a82/t/672f62b6310c452ac0aa3ddb/1731158711171/Bizantheum.otf' ); }
//Assign Bizantheum Font//
h1{font-family: 'Bizantheum';}
h2{font-family: 'Bizantheum';}
h3{font-family: 'Bizantheum';}
h4{font-family: 'Bizantheum';}

//2nd Font//

  font-family:'Fontfabric-MullerRegular'
