I
am overseeing about 17 sections that are using WeBWorK, of which 12 are
sections of Pre-Calculus. One instructor has reported that two of his
students have gotten the same error message for the same problem
template. Logging-in as an administrator, I have a proper rendering of
the problem, but when I act as one of these students, I get the error
message attached below.
I'd appreciate any suggestions as to the cause of WeBWorK's inability to render the problem for some students but not all.
Thank you.

% ERROR in :EV3, PGbasicmacros.pl:
% There is an error occuring in the following code:
Seven points in the plane are given below. Find the regression
equation, letting the first variable be the independent x variable, and
predict the y value when x is $tall . \begin{array}{c|ccccccc} \mbox{x}
& $sh[0] & $sh[1] & $sh[2] & $sh[3] & $sh[4] &
$sh[5] & $sh[6] \cr \hline \mbox{y} & $sw[0] & $sw[1] &
$sw[2] & $sw[3] & $sw[4] & $sw[5] & $sw[6] \cr
\end{array}
The regression equation is y = +\ x .
The best predicted y value(from the regression equation) when x is $tall is .
