switch statement - My Javascript doesn't work -

i wrote simple program following example book. it's supposed draw dice random number of dots doesn't work. found problem caused simple "switch" instruction.

thing downloaded program author's page , work. after slight adjustment in formatting code identical it's still broken.

it nice if tell me if going on.

this how code looks (and doesn't work): http://pastebin.com/1hjwpxi8

this author's: http://faculty.purchase.edu/jeanine.meyer/html5/dice1.html

i found if copy/paste "switch" instruction author's code mine starts working properly.

problem here:

                case 5;                  draw4();                  draw1();                  break;                 case 6;                  draw4();                  draw2mid();                  break; 

cases in switch statement followed colon, not semi-colon. replace case 5; case 5:, case 6; case 6:...

and code work.
