 Overview - This box is used to create a rule that determines whether or not a submitted graph is correct.  In general, it takes the form of testing the function, its integral, or its first or second derivative over a given set of x-values.  The test can be to see if it equals, is greater than, or less than a specified value.  Anywhere a number is needed, a variable can also be used.  (Skip to the bottom for examples of rules.)
 
 \begin{itemize}
-\item ``Index/Name" - This is an internal label for the rule.  Something must be entered here, and it must be different for each rule.  This same value will be used to add a conditional hint.

 \item ``Initial x-value'' and ``Initial x-value label'' - A value must be entered for one of these.  Either choose a numerical value for x (the first option), or choose the beginning of the submitted answer, the end, or a previously chosen named point (see below).

 \item ``Relationship''  - The heart of the rule.  This choice determines whether the chosen `Function' is greater than, less than, equal to, etc. a certain `Value'.
 
-\item ``Value'' - Enter the number you wish to compare to.  It is also possible to choose 'not defined', in the event the answer should not have a value for the given domain. Within the value argument, the function itself can be evaluated using \&fpr\_f(), its derivative using \&fpr\_dfdx(), and its second derivative using \&fpr\_d2fdx2(). This allows for a comparison of two points on the graph.  The value of a previously defined label can be retrieved using the function \&fpr\_val(), e.g., \&fpr\_val(`positive'). Previous defined values from script blocks can also be retrieved as normal variables, e.g., \$x.

 \item ``Percent error'' - This allows for a margin of error in the y-direction.  For instance, if the rule requires that the derivative be equal to 5, the server will accept values close enough to 5 that are within the percent error defined here. Note: Choosing 10\% would not mean that the answer is correct as long as it is within the range 4.5-5.5.  Instead, the percent corresponds to the total size of the graph.  For the function itself, the `percent error' is multiplied by the ymax-ymin; for the first derivative, it's multiplied by (ymax-ymin)/(xmax-xmin); for the second derivative, it's multiplied by (ymax-ymin)/(xmax-xmin)$^2$; and for the integral, it's multiplied by (ymax-ymin)*(xmax-xmin).
