Need help with my moms Subie

Maybe im missing something here but the belt has to go on a certain way…

Well not so much the belt but it has marks on it so that you align the camshaft pulleys and crackshaft pulley where their supposed to be, you cant just take the old one off, slap the new one and and be all dandy…

Wait i read it again… So you put the new belt on any which way it slid on the first time you tried to crank it over again? and now after doing so your trying to line up the belts timing marks with the cams/crank? :ohnoes
