here you didn't specify that which type of build you're trying with, if it's webplayer build, hope this link will help you.

Is there a way to replace the 'http://' content with a variable and still allow the ExternalEval to work properly???
public var linkURL = "http://www.google.com";
Application.ExternalEval("window.open( linkURL, '_blank');"); ... does not work
So far I've been slightly unsucessful in overcoming this. Anyone know how to solve this issue???
