Ice Floes Macro

Hey guys, my old castsequence macro I had for icefloes is no longer working and I can’t figure out how to do what I need to do. What I’m trying to accomplish is: create a macro that I can bind to my scroll wheel that will only use 1 stack of icefloes at a time.

My issue currently is that any variation of “/castsequence reset=1 ice floes,null,null” is no longer keeping the spell from using 2 charges at a time. Hlep!
