Are you being serious right now? I find it hard to believe that you would take all the time to post this question before checking the simplest of HTML syntax. SO even highlights the problem in your code. I can understand being confused between when to use ' and when to use " - but your href url isn't enclosed in either!
Try using something like JSLint, it can force you to write cleaner, "syntactically safe" code. Run it manually (jslint.com) or get a plugin for your IDE / text editor.
