You cant find the seventh gym in emerald version how do you get to it

http://db.gamefaqs.com/portable/gbadvance/file/pokemon_emerald_c.txt Thats a walkthrough that I used to help me with my game, when or if you go there press Ctrl+F and type in PEW65. and press enter two times. That should bring you to the sectio about Route 127, if you have'nt defeated Team Magma yet then scroll up a little more. I hope this helps you.
