If you are working on a subdirectory, check the parent directories, as variables will be searched for in the current directory, and all its parents all the way up to HOME.
So if you don't find the variable in VARS, do UPDIR and see if they are there, and keep looking until you get to HOME.
I bet you left those defined in one of the parents.
