Subscript

Please look at the second paragraph in the attached file. Several sentences from the top is axial load L_{a, m}

When I enclose it in Nemeth indicators and translate it into Duxbury I get and ow sign in front of the m. There is no comma shown.

I am sending a braille file to show what I think it should look like. Am I right?

The first example is the way Duxbury translated the line. The second example is the way I think it should look.

Thank you,

Susan
