Dear David,

    Actually the underscore sign you are putting is the problem. If you
put the underscore sign it would directly get into the mathmode, and also
not putting the $ sign. You can use any other symbols instead of this
underscore sign like hiphen and then run it. I have here tested and was
not showing any errors. Hope you get it.

Best,
K.S. Mithran
