Hi David,
I'm confused; the script you sent is different than the code snipet in your note, and indeed the script looks to be correct:
f = addfiles(FILES+".nc","r")
times = wrf_user_getvar(f,"times",-1) ; get all times in the file
ntimes = dimsizes(times) ; number of times in the file
In particular, notice the script contains the file-variable "f", rather than "a" in the snipet (I believe "a" is used as an example of the docs page for wrf_user_getvar()). There is no variable "a" anywhere in the script.

I've searched the archives for similar errors experienced by other users and nothing has proven to be the solution yet.
