How can I make this initiative macro exploding ? World of darkness. d10 system.

I have an initiative tracker . reduces successes on a  1. How do I make it explode on a 10?  So far it works except it wont add exploding dice on a 10 and I cant tell why.   Im obviously missing something. I cant really make out where to add the !! command.  Sorry for my lack of techyness  ;)  /r (@{selected|Wits}+@{selected|Alertness})d10>4f1 &{tracker}

You just need to add an exclamation mark after the f1 /r (@{selected|Wits}+@{selected|Alertness})d10>4f1! &{tracker} should work.

Thanks for that .  I thought Id tried that. But I obviously messed up. Thanks for your help ++
