How to open current working directory if a certain folder doesn't exists in the directory?

So here is my code on a pushbutton callback:
prompt = {'Enter Patient Name or ID:'};
title = 'Input';
num_lines = 1;
defaultans = {'Patient'};
answer = inputdlg(prompt,title,num_lines,defaultans);
handles.file = cellstr(answer{1});
%Creating a new folder by the name of Patient's name that user entered
folder = handles.file{1}
guidata(hObject, handles);
mkdir(folder);
By far its working fine, now in a different pushbutton callback I want to display an error if the folder of same name already exists
folder = handles.file{1}
if exist(folder,'dir')
winopen(folder);
else
winopen(pwd);
end
But it shows error : Reference to non-existent field 'file'. Please Help. Thanks in advance

Evidently your first function didn't execute so that file is not a new field attached to handles. Or guidata() didn't work, but that seems doubtful. Examine handles in the second function before it bombs (set a breakpoint) and make sure that file is a field that is still attached to handles.

Yes that's right. If you push the second button without pushing the first button first, then file will not be attached to handles yet.
