How Do I get through Icefall cave I can't find the way to the other ladder..

Just keep on trying. You'll get there before long.

This is Rayblackza, try this:

Once you're in Icefall Cave, surf across the water and go deeper. In this room, you'll find a puzzle with many blue ice tiles. They are just thin pieces of ice that crack the first time you step on it, and break the second time. This is a fairly easy puzzle. You want to get to the bottom-right corner of this room, where you'll find HM07 - Waterfall. You want to fall through certain holes to get to the HM, and after some trial and error, you'll get to it.

After getting the HM, teach it to a Pokemon, exit this room and go up the waterfall. Go up the ladder, into the entrance, and you'll find Lorelei defending the Pokemon of this cave from Team Rocket. She'll then drag you into the argument, and you'll have to fight a Rocket member.

Obtain HM07 (Waterfall) in the room of the cave above the ice floors and use it to scale the waterfall in the cave's foyer. Go down the ladder at the top of the waterfall, go in the cave, and you will find Lorelei and a few Rockets.

When I go into the room with lorele she says nothing and I can't talk to the rocket members I gave the ruby to celio I'm stumped I can't progress help
