MATLAB: Using if else in a loop

elseif for

Hi,
I'm struggling a lot with a small part of my code, hope someone could help me out with it.
Basically, on the first elseif step, I want to add values from a matrix called Table2 when t>24, but I'm only getting values from the first if, which makes no sense to me.
y = 8;
x = 24;
for t = 9:48;
    if t <= x
       Temp_v(t) = Table(t,6) + Table2(t-y,6) - Table(t-y,6);
    elseif x < t <= x+y
       Temp_v(t) =  Table(t,6) + Table2(t-8,6) - Table(t-8,6)+ Table(t-24,6) - Table2(t-x,6);
    else 
       Temp_v(t) =  Table(t,6) + Table2(t-y,6) - Table(t-y,6)+ Table(t-x,6) - Table2(t-x,6)+ Table2(t-(x+y),6) - Table(t-(x+y),6);
    end
   
end
Thanks!

This
x < t <= x+y
should be 
(x < t) && (t <= x+y)
Here's a demo that shows why the first line fails. 
% This returns TRUE even though 5 is not less than 4
5 < 4 <= 8+1 
% The reason is that the left side is evaluated first 
5 < 4  % = false(0)
0 <= 8+1  % = true
