How to display MAPE in gui?

for example value for mape is 50:

 mape = 50;
 set(handles.text10,'String','MAPE = '+mape_2);

In GUI I have lot of different values, but I need only one value - 50. Please I need help!

and mape as text is not here too. I have only this on my gui - picture

Dominika - why is one variable named mape but then you reference mape_2 where you set the string of the text10 control? If you are trying to update the text string with a combination of 'MAPE =' and 50 then try doing the following

 mape = 50;
 set(handles.text10, 'String', ['MAPE = ' num2str(mape)]);

In the above, we use num2str to convert the number into a string and then concatenate it with 'MAPE =' using the square brackets.

Works. :) Thank you very much
