loop on handles on GUI

I have issue to perform a loop on handles in a GUI

I have 9 checkboxs named checkbox1....checkbox9. I can easily access to values

I tried to do that :

for i= 1: 9
    temp=strcat('handles.checkbox',num2str(i));
    if get(temp,'Value')==1;
       pooled_values= pooled_values+values(i,:);
    end
end

I also tried to convert the string to a function handle with "str2func"

So obviously a strinf isn't an handle and I am wondering how to do what I want ?

Thank you for the help
