It's often best to build up a Module gradually. Get little fragments of it working outside a Module, in individual cells. Then start combining steps in one cell. Then when THAT is working, put it into a Module. Another thing that's very helpful is to put Print statements in your Module, so that you can see exactly what's happening. If you want to know what this or that fragment does, name the result of that fragment (which you have probably done already anyway) and print it. Sometimes I'll print the output of nearly every line of code in a Module, to see exactly what's going on at each step. Once it's all working, take out all the extra Print statements. -- Helen Read University of Vermont
