Hello,

I'm creating a GUI in which I import data from an Excel and I want the name of the columns to appear as options in a pop-up menu. The problem is that it doesn't happen and an error appear. What can I do? I think the error is in the last line but I do not know how to solve it.

Thank you very much!!! Pedro

This is my code:

   function datagraphV1
   f=figure('Visible','off','Position',[100,100,450,285]);
   hload=uicontrol('Style', 'pushbutton',...
    'String','Load .xlsx','Position',[315,220,70,25],...
    'Callback',{@loadbutton_Callback});
   hpopupX=uicontrol('Style','popupmenu',...
    'String',{'popupmenuX'},...
    'Position',[300,75,100,25],...
    'Callback',{@popupX_Callback});
   function loadbutton_Callback(hObject,eventdata,handles) %Function callback for loading the Excel and changing the 
  pop-up menu X.
   handles.filename=uigetfile('*.xlsx');
   guidata(hObject,handles);
   [Comp, Prod, OthInfo, colnames,numcolum]=extractdataexcelV2(handles.filename);
   hpopupX.String=colnames;
