This message is telling you Cartesian is already defined before loading the package On a freshly started session try ?Cartesian. Do you get a Information:notfound error, indicating the symbol Cartesian isn't found? If so, now try loading the package. Do you still get the error you reported above? If you don't get a Information:notfound error when you do ?Cartesian, do you get a help message describing Cartesian? Other things to try are $ContextPath which will give you a listing of all contexts available in the current session. ??Cartesian which will tell you what context Cartesian is defined in and any definitions associated with Cartesian > In[2]:= <<GraphicsPlotField3D > <<GraphicsPlotField > <<GraphicsContourPlot3D > <<GraphicsLegend This also looks strange. If these are indeed loading the packages you must have a non-standard installation of Mathematica. A quick check of the resources I have handy shows the package Calculus`VectorAnalysis` appears to be the same in both version 3.0 and 5.0. So, I doubt the differences between version 4.1 and 4.2 are the cause of you problem. -- To reply via email subtract one hundred and nine -- To reply via email subtract one hundred and nine
