Not working

Not sure if it’s not working or if I just can’t figure out how to work it. The program isn’t intuitive and there’s no how-to’s to follow for installation. But I uploaded a FontSquirrel font and am not able to use it. It’s showing in the box, but I don’t know how to select it or activate it. Tried adding the name manually to the CSS, but nothing is happening.

Would appreciate some assistance. Thank you.
