The command can fail if lnCount is of the wrong type. Separate this into two commands:

local lcMessage
lcMessage = "Working on record: " + str(lnCount)
wait window lcMessage timeout 0.2

Or use trans() instead of str():

wait window "Working on record: " + trans(lnCount) timeout 0.2

Also, why the timeout?

scan
  wait window "Working on record: " + trans(lnCount) nowait
endscan
wait clear
