How can I copy the programm?

Hey guys,

I have got some questions. I am a newbie working with guis. Reading the matlab help I found following programm:

http://de.mathworks.com/help/matlab/creating_guis/plot-workspace-variables-in-a-guide-gui.html

In this link its said to copy the words below into the command window.

    copyfile(fullfile(docroot, 'techdoc','creating_guis',... 
    'examples','lb.*')), fileattrib('lb.*', '+w') 
    guide lb.fig

By doing this a programm opens. With this programm you can insert the variables of the workspace in a listbox. From this listbox you can choose two variables and you can plot them.

When I try to make the same programm, and copy the whole stuff, I dont get the listbox, where the variables of the workspace should be. Also I get one warning:

    Warning: Single-selection 'listbox' control requires a scalar Value. 
    Control will not be rendered until all of its parameter values are valid

I dont know why I get this warning. How can I fix this?

Thanks in advance.

Kind regards Frederic

"Also I get one warning:" &nbsp See the Uicontrol Property, max &nbsp In a table down the page you'll find

'listbox'

    The Max property value helps determine whether the user can select multiple 
    items in the list box simultaneously. If Max – Min > 1, then the user can 
    select multiple items simultaneously. If Max – Min ≤ 1, then the user cannot 
    select multiple items simultaneously. If you set the Max and Min properties 
    to allow multiple selections, then the Value property value can be a vector 
    of indices.
