Problems with legend

hello, in my program i have the following plots:

u = [0.4 mnd12005lu];
    q = mnd12005sd;
    g = [q(1:end-2) ;q(2:end-1); q(3:end)];
    t = [0 0 0]; % vektor for de tre første dager (29. des, 1 og 2 jan) for snødybde ved bruk til kristiansentrippel.

    zeiglersum = ((2*pi).*mnd12005lu' + 3.6.*mnd12005sd')';
    foerdesfaktor = (4.7.*mnd12005lu' + 0.3.*mnd12005sd'.^2)';
    grinismaksimum = max(u(1:end-1),u(2:end));
    kristiansenstrippel = [mean(t) mean(g)];
    hennestadsminimum = min (zeiglersum, grinismaksimum) - 5;

    plot (zeiglersum, 'k-')
    axis([0 32 -inf inf])
    legend ('zeiglersum','foerdesfaktor,'-4.*grinismaksimum', '3.*kristiansenstrippel', 'hennestadsminimum')

    hold on

    plot(foerdesfaktor, 'm --','linewidth',2)

    hold on

    plot(-4.*grinismaksimum, 'c : .')

    hold on

    plot(3.*kristiansenstrippel, 'r -.')

    hold on

    plot(hennestadsminimum,  'g :')

    hold off

When i run the plot, only the legend for 'zeiglersum' shows up. i also get the following message:

Warning: Ignoring extra legend entries. > In legend at 294 In OBLIG2 at 63

OBLIG2 is the program

Move the legend() call to below the place you plot the last value.

I believe, by the way, that you are missing an "'" immediately after "'foerdesfaktor" in your legend() call.

Hmm, intial walkthorugh your code

     legend ('zeiglersum','foerdesfaktor,'-4.*grinismaksimum',   
 '3.*kristiansenstrippel', 'hennestadsminimum')

in the legend line you have not completed tick for 'foerdesfaktor'

the line should read:

   legend ('zeiglersum','foerdesfaktor','-4.*grinismaksimum', '3.*kristiansenstrippel', 'hennestadsminimum')

ive changed that and still it wont work
