Custom font code written but font not changing

@fbogus There should be commas between urls

Your code is

@font-face {
       font-family: 'gooddog';
       src: url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df62bcf8a3400014e88f9/1563293227668/gooddp__-webfont.woff) url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df688c27c1c00012438c8/1563293320236/gooddp__-webfont.woff2) url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df6ad0a52970001c7cd98/1563293357257/GOODDP__.TTF)
   }

It should be

@font-face {
   font-family: 'gooddog';
   src: 
   url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df62bcf8a3400014e88f9/1563293227668/gooddp__-webfont.woff), url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df688c27c1c00012438c8/1563293320236/gooddp__-webfont.woff2), url(https://static1.squarespace.com/static/5d279557b233000001390e62/t/5d2df6ad0a52970001c7cd98/1563293357257/GOODDP__.TTF);
}

Can you post all code you inserted? or post screenshot?

h1{ font-family: 'gooddog', 'gibson',sans-serif !important; }

@tuanphan The only change I saw is adding the code !important

I made that change and it had no effect that I could see.

Did you add @font-face?

Yes, it is there. Still no change.

Please provide a working link to the website.

It's almost impossible to troubleshoot code unless the community have a working link to your website. Without this we cannot see the code being used or any errors that are being generated.

If your site is still in trial mode you will need to set a site password and tell us what it is.

Can you share site url?

I am still in trial mode. I will try to figure out how to set a password.

Thank you! That made all the difference.
I am not detail-oriented enough to be doing this regularly.
