Trying this plot command Plot[p^2/((p^2 - k^2) (p^2 + m^2)), {p, 0, k}] and Mathematica gives some cryptic message!

I am not quite sure what you want to achieve, but this might help: Manipulate[If[k == 0, "Not Defined", Plot[p^2/((p^2 - k^2) (p^2 + m^2)), {p, 0, k}]], {m, -10, 10}, {k, -10, 10}] To plot the function it "pre-sets" m and k for you, but you can change them with the sliders. I also added a "not defined" output when k==0. M.

Plot can not be called with multiple variables. Only one.

I think the function you want to plot consist in three variables, so plot is as follows Plot[f[x,y,z],{x,xmin,xmax},{y,ymin,ymax},{z,zmin,zmax}] in your case the vairables are m,k,p but maybe one of them is constant or two of them. you know If is three dimensional is Plot3D[.....]
