Hi;

In the function that I am using x is undefined at value 3 (see attached). To circumvent the problem of x being undefined, I created a piecewise function defining x at value 3 to be zero and subsequently created a table using the piecewise function. When the table executes, I am receiving the message "Set::setraw: Cannot assign to raw object 3.`." and do not understand why. Is there anything I need to do to get rid of the message or just live with it?

Another unrelated question - how can I past code from a notebook into this forum. All of my pasting using Ctrl V (from windows) looks awful.

Thanks,

Mitch Sandlin
