Problem with pop n shredder

Hey guyz, im new here , and im trying to learn some basics of dante and putting him into my team , but i’m having a problem with the pop shredder , since im droping the combo in the middle of it, any clue?
ps:the combo i make is stL-stM-S-airM-airM-airH-airS-coldshower-pop’n’shredder-jumpteleport-hammer-volcano to bee hive-guitar(forgot name)-fireworks-million dollars.
is it ok for a beginner?
