Problem with Action Recorder

I've just started working with the action recorder and the very first Action I tried failed. It recorded fine but errors out when I try to call it.

I'm trying to play back the following Action which is named "XPL":
command->Xplode
-I select my block and hit enter
-I type "la" to xplode it to a layer
-I hit enter to accept the default(however I have also tried recording it with a specific layer entered)
-I hit enter to finish the command

The following error is returned when I call the Action:
Command Failed "Xplode"
Command:z*Cancel*
Command:*Cancel*
Command:XPL

What's going on?
