I am creating a robot maze. I have a edit box that i want to be able to a number of steps I want the robot to take and when I press the push button I want it to take the number of steps in the edit box. What I have now opens a new tab I dont know how to do what I wanna do

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', @stepLeft)
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', @stepBack)
sixth_button = uicontrol('style', 'pushbutton');
set(sixth_button, 'units', 'normalized', 'position', [0.6, 0.5, 0.2, 0.2])
set(sixth_button, 'string', 'right')
set(sixth_button, 'callback',@stepRight)
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!')
set(ninth_button, 'callback', @Run)
function toggleHistory(sender, eventdata)
if sender.Value == 1
    disp showHistory
else 
    disp hideHistory
end 
end 
function Run(sender,eventdate)
    step_input = ('edit; string')';
    if ~strcmp(edit, '')
    number_of_steps = str2num(step_input);
    walk(number_of_steps); 
    end 
end

Are you using App Designer or GUIDE? Please attach your .mlapp file if using App Designer or .m and .fig files if you're using GUIDE.

Is what you call "eight_button" actually an edit field instead of a push button???

Exactly what does "taking a number of steps" mean? I have no idea what that would do in terms of changing some variable or changing the appearance of something on a GUI.

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:
