Controlling stepper with an Android app through Yún

Hello everybody,

This is my first post, so sorry if I break any rules :-).

I am working on a school project, where we are using an Arduino Yún to control a solenoid, a stepper and a sensor.
These three components are controlled through an Android app that i have created in MIT App inventor.

However i have not yet been succesful about getting the stepper to work with the setup? The hope is to make the stepper take a number of steps when clicking a button (perhaps by going to an IP adress, ex: 192.168.0.10//arduino/digital/9/1 or the like - as I have done it with the other component).

I have the Yún connected to a homemade motor-controlling board, using the stepper library, and i normally just use the different examples from there, but can't quite get them to work by inserting parts of the code into the bridge sketch.

I have attached the sketch that I am using as of now.

Thanks in advance,
Anders
