I'm trying to create 2 popup menus the first one stores all the 'Y numbers' and then depending on that I want to get the corressponding 'Version'. Note some Y numbers have more than 1 version. Hence I need help to figure it out

Your code will generate a variable of the dataset class (which will apparently be removed in a future release), while your screenshot is of the table datatype. The data also doesn't look remotely similar to me. Should the first dropdown contain 0.1, 0.3, and 0.2, with the second dropdown containing only a single option after the first selection has been made?

Ynumber=[1;1;2;3;5];
Version={'AP'; 'AP_R' ;'AP' ;'TI1' ;'TI2'};
mytable= table(Ynumber,Version);
%Y_selected=get(handles.dropdown_Y,'Value');
Y_selected=2;
selected_Ynumber=mytable.Ynumber(Y_selected);
L=ismember(mytable.Ynumber,selected_Ynumber);
versions=mytable.Version(L);
The last variable can be used as the String property of your second dropdown.

sorry not that line but this;
selected_Ynumber=data_sheet2.YNumber(Y_selected); -----------(Error: Expected one output from a curly brace or dot indexing expression, but there were 12475 results.)
L=ismember(data_sheet2.YNumber,selected_Ynumber);
handles.popupmenu2.String=b(L);

The code I posted works. You can't send me the data you're working with, so you will have to provide example data that will reproduce the error. It seems like Y_selected might not be a scalar, or data_sheet2 is not a table or scalar struct.
