[Help] Remote Controlled Batarang

[BullsEye]

Hi everyone

First of all, i would like to ask forgiveness if my english isn't the best, but i'm Portuguese, and that's not my main language.

I'm having a problem where i need your help.

I'm at the mission where i need to get the cure from Joker, but i've reached a place where i can't pass through. I've to throw the Remote Controlled Batarang to the electrical button to open the gates under me, where the water passes, and then create an ice platform to pass under where i'm at right now.
I've throwned the Remote Controlled Batarang, and hitted the button, but the gates don't open...

Can't you help to pass this obstacle?

Thank you very much.

ok! When you get on that that platform, you should see a electrical thing. its a little through the gate where you throw the batarang. Go through the current of electricity and then hit the button.
