\label{Spreadsheet_Max_Depth_Exceeded}
The ``Maximum Calculation Depth Exceeded''\index{Maximum Calculation
Depth Exceeded error} error can occur when you reference other cells in
calculations. For example, if you have: 

\texttt{G0 = Some\_complicated\_expression\\
 X0 = G0>2?1:0}

Try replacing \texttt{X0}'s contents with \texttt{[
(Some\_complicated\_expression) > 2]?1:0}. In other words, replace the
reference to \texttt{G0} with the actual contents of \texttt{G0}. That
might fix your error by removing one level of indirection that
LON-CAPA must process in order to compute the result.
