Syntax error in a Simulink Fcn block

I am getting a syntax error message for the expression "FiringOrder(u)" (no quotes) in a Fcn block. "FiringOrder" is a 1 x 6 row vector in the base workspace. (I have also tried it with "FiringOrder" defined as a row vector in the model workspace, with the same result--syntax error.) The input is a single value that I'm trying to use to index into the array, outputting the value at the "u'th" column in the row vector.
The help documentation for the Fcn block says that Simulink searches for function names in the expression, and then looks in the MATLAB base workspace, so it should be finding the row vector FiringOrder. I've tried adding the vector as a parameter in the model workspace, and that doesn't work either. This expression is so simple that I can't believe I'm getting a syntax error, but I am. What am I doing wrong??
Thanks.

Since FiringOrder is an array in your workspace, it would not be recognized as a function in MATLAB.
To achieve your objective, try replacing the Fcn block with the block "1-D Look up Table" (See Documentation).
Set the Table Data as FiringOrder and the breakpoints as 1:6.
