I'm trying to create a multitude of 8×8 grids with a single random shaded box on each. This is for a classroom activity and I want a bunch of different grids and would rather not hard-code the random box for each one. I'm using the following code:
\begin{tikzpicture}[x=2.54cm, y=2.54cm]
\foreach \y in {1,2,...,8}
{
\foreach \x in {1,2,...,8}
{
\ifthenelse{\x= \pgfmathparse{random(8)}\pgfmathresult \AND \y=\pgfmathparse{random(8)}\pgfmathresult}
{\filldraw[draw=black,fill=lightgray] (\x,\y) rectangle (\x,\y) rectangle (1+\x,1+\y);}
{\draw[black] (\x,\y) rectangle (\x,\y) rectangle (1+\x,1+\y);}
}
}
\end{tikzpicture}
And I get the error
Incomplete \iffalse; all text was ignored after line 51"
where line 51 is that close curly brace before the \end{tikzpicture}
. I've looked around for a fix but haven't discovered one yet.

Just fleshing out David's comments.
And @cfr is right, but this also works.
