simple math with wrong results results

so i'm trying to reproduce some homework nothing too complicated ,simple stuff , when applying the formula for E i'm receiving 1 value 0.7018 , i tried writing the vectors P_ref and P_m as colums i ran the program again and i'm getting some weird values which i attached in an ss ,everything else gives the desired values ,if i manually do the multiplication and divisionin command window i get the desired value .What did i do wrong ?

%% input 
L_et=6; %   Measurement limit for the standard manometer
L_m=6;  %  Measuring limit for checked manometer
et=.6;  %     Precision class for the standard manometer
em=1.6; %  Precision class for the checked manomenter
P_ref=[0.75 ;   1.5;    2.25 ;  3;        3.75;   4.5 ;    4.5;   3.75 ;   3 ;       2.25;   1.5 ;    0.75;];
P_m=  [0.76;   1.55;  2.3;     3.08;  3.84;   4.58;  4.58;  3.67;    2.92;   2.18;   1.45;   0.748;]
%% calculus
disp("the maximum value of the absolute measurement error for the  standard manometer e_lim_m ")
e_lim_et=L_et*(et/100);

disp(" the maximum value of the absolute measurement error for the manometer to be checked by e_lim_m ")
e_lim_m=L_m*(em/100);

disp(" absolute measurement error  e ")
e=P_m-P_ref

disp(" relative measurement error E ")
E=(e/P_ref)*100

disp(" total relative measurement error Et ")
Et=(e/L_m)*100

thx , i totally forgot about the .
