Font Help

Hi! Love this plug-in but need some font support. Either of these aren’t working for me so my font doesn’t show up consistently (defaults to a plain font). Need help since it’s for sure my error.

font-family: ‘Muller-Medium’;
src: url(‘webFonts/Muller-Medium/font.woff2’) format(‘woff2’), url(‘webFonts/Muller-Medium/font.woff’) format(‘woff’);

OR

.Muller-Regular {
font-family: Muller-Regular;
}
