Unexpected token 'X' found at position Y

The following expression is throwing the exception "Unexpected token '123' found at position 15" and I cannot for the life of me figure out why. It seems like a legit expression.

(123>1) ? (min(123, max((80/100) * 123,1))) : (1)

It doesn't matter what number I use in place of 123 -- I get the same result. What am I missing?

I am using muParser v2.3.4 (Release).

My bad. I had the wrong character in the call to SetArgSep.
