Step: 5 defining codes

ive done with step 4, managed to save it. done with step 5, learned how to define codes but didnt managed to save it even when i saved it as step5.gvr... i think theres a bug because i saved it, reopened it and it works but when i close gvr and reopen a new gvr, the files doesnt show. today i learned that guido can learn new stuffs but needs a definition to the new action. -cheers
