Thank you both for your replies. I tried both soulutions

a=[1 2 1 2];
bgcols = [.5, 0, 0;1,1,0];
arrayfun(@(idx) set(handles.t(idx),'BackgroundColor', bgcols(a(idx),:)),1:length(handles.t));

a=[1 2 1 2]; %1 or 2
for i=1:4
if a(i)==1
set(handles.t(i),'BackgroundColor',[.5,0,0])
elseif a(i)==2
set(handles.t(i),'BackgroundColor',[1,1,0])
end
end

But i still get the same message.

??? Reference to non-existent field 't'.

Any Ideas? Thanks
