why am i getting this error? I've changed it so many times

Funct definitions in a seriat must appear at the end of the File. Move all statements after the function de to before the first ladat fonction definition b) Use the function defined in part a to generate a plot of the probability vs. the temperature for three different values of the energy splitting (1 x 10-V. IX 10-eV and 5 x 10 eV). Your final plot should have three different curves corresponding to the three energy splittings and should cover the temperature range from 0 to 100 K sure your axes are reasonable and the plot is properly labeled 50 Temperatura: 1803 51 52 plot(tenperature, prob (10^-6, temperature: 53 54 hold on 55 56 plot(tenperature, probl10^-5, temperature)); 57 58 plot(temperature, probl5.10^-5, temperature): 50 60 Klabel("Temperature); labelling y axis as Temperature 62 ylabel("Probability"; labelling y axis as probability legendf"18-6",1104-5","5x10^-5): Making Legends COMMAND WINDOW Funct definitions in a seriat must appear at the end of the File.
