Castlevania PLEASE HELP ME!!!!!!!?

ok I killed the huge skeleton and now I'm trying to unlock the iron cate well I know you have to jump on top of the temple things but I can only jump on 1 and when I try the 2nd I can never make it...it seems like a impossible jump! plz someone help me b4 I throw this game out the window! I'm playing it on nintendo 64 and I've tried IGN.com but all is tells me is to jump to the other one and I already know that I've tried and tried again to make in across to the other temple but I just keep falling!
