[Automysqlbackup-users] Undefined Variable?

[Tom <to...@co...>]

In the output below, the "Rotating 4 month backups for" line in both the
"Dump full schema." and "Dump status." sections is blank because the $(mdb)
variable is undefined.
That variable is on lines  1752, 1770, 1787, 1816, 1834 and 1851.
That's too many lines to just be typo.
How can I fix this? Any help would be appreciated.
