Maria, do you mind sharing the error message so that I could have a better sense about what's going on?

My suspicion is that you code the "run" column with square brackets in the labels. However, in your "glt" and "glf" coding, the square brackets are not used. I would drop the square brackets in the "run" column.

A side note: those 6 "glf" lines can be treated as "glt".
