Syntax error

hello, when i switch to publish for flash player 8 instead of flash player 7 in the publish settings, i get an error when i test my movie;

Error Scene=Main, layer=actions, frame=1:Line 1: Syntax error.
percentage = Math.round((_root.getBytesLoaded()/_root.getBytesTotal())*100) add “% loaded”;

Total ActionScript Errors: 1 Reported Errors: 1

any suggestions?

thanks!
