Parse Error and unrecognized media only css validation

Question

Css wont validate and I keep getting these errors. I have an ending bracket, so I'm not sure what the problem is. There's a parse error on line 39. Unrecognized media only on lines 79 and 81. Then on lines 79 and 89 those have the parse error. If anyone could help that would be greatly appreciated.

39.    nav a:{text-decoration:none;
    font-weight: bold;  }

nav a:link {color: #ffffff;}
