 functions: They take some number of arguments in, and return one argument,
 usually a number or a string for our purposes. There are a lot of functions
 available in LON-CAPA. You can see a complete list at
-\ref{all functions table}.
+\ref{Script_Functions}.
 
 For now, let's just look at some simple examples.

 In the \textbf{Script} block, function names start with \textbf{\&}. Some
-example function calls are shown in figure \ref{Some Function Calls Figure}.
+example function calls are shown above.
 You can see that functions can take either variables, numbers, or the results
 of other function calls as parameters. The \texttt{\&sin} function returns
 the sine of an angle expressed in radians. \texttt{\&pow} raises the first
