I need help writing a script for an edit box

I need help writing a script for and edit box and button. When the button is pressed I need my robot to walk forward as many steps specified in the edit box. I need to write a call back function for the button where it reads the edit box and then calls walk from the robot inter face to go that many steps.

createRandomMaze
figure;
first_button = uicontrol('style', 'pushbutton');
set(first_button, 'units', 'normalized', 'position', [0.2,0.7, 0.2, 0.2])
set(first_button, 'string', 'turn left')
set(first_button, 'callback', @turnLeft)
second_button = uicontrol('style', 'pushbutton');
set(second_button, 'units', 'normalized', 'position', [0.4, 0.7, 0.2, 0.2])
set(second_button, 'string', 'step')
set(second_button, 'callback', @step)
third_button = uicontrol('style', 'pushbutton');
set(third_button, 'units', 'normalized', 'position', [0.6, 0.7, 0.2, 0.2])
set(third_button, 'string', 'turn right')
set(third_button, 'callback', @turnRight)
fourth_button = uicontrol('style', 'pushbutton');
set(fourth_button, 'units', 'normalized', 'position', [0.2, 0.5, 0.2, 0.2])
set(fourth_button, 'string', 'left')
set(fourth_button, 'callback', @turnLeft)
fifth_button = uicontrol('style', 'pushbutton');
set(fifth_button, 'units', 'normalized', 'position', [0.4, 0.5, 0.2, 0.2])
set(fifth_button, 'string', 'back')
set(fifth_button, 'callback', @step)
sixth_button = uicontrol('style', 'pushbutton');
set(sixth_button, 'units', 'normalized', 'position', [0.6, 0.5, 0.2, 0.2])
set(sixth_button, 'string', 'right')
seventh_button = uicontrol ('style','checkbox');
set(seventh_button, 'units', 'normalized', 'position', [0.2, 0.3, 0.2, 0.2])
set(seventh_button, 'string', 'History')
set(seventh_button, 'callback', @toggleHistory)
eighth_button = uicontrol ('style', 'edit');
set(eighth_button, 'units', 'normalized', 'position', [0.4, 0.37, 0.2, 0.05])
set(eighth_button, 'string', '2')
ninth_button = uicontrol('style','pushbutton');
set(ninth_button, 'units', 'normalized', 'position', [0.6, 0.3, 0.2, 0.2])
set(ninth_button, 'string', 'Run!')
function toggleHistory(sender, evendata)
if sender.Value == 1
    disp showHistory
else 
    disp hideHistory
end 
end 

This is what I have created so far

Why are you numbering your buttons instead of giving them names? And why are you not storing the handles in a struct in the guidata?

For general advice and examples for how to create a GUI, have look at this thread. It seems you are doing some of the right things already, but you need to make a cohesive whole. You should also remember to always use explicit parents when creating or modifying graphics object when dealing with a GUI.
