You're missing quotes. Two sets. You probably also want && between
the two commands, to check for the success of the mkdir before attempting
a cd.

Where do these variables (YEAR, MTH, DOYR) come from?

How/where did you set it?

We don't know, because you haven't shown us where you're setting it.

Because you used mkdir -p. Please read what -p does.

A cron job will not inherit those variables from your shell session,
or wherever it is you're defining them. You'll have to set them within
the cron job, or use the date(1) command, or use bash's printf %()T
formatter to generate date/time strings.
