Add Sound Effects to Spells

Trying to add sound effects to my players spells with roll20AM. Using the following script wording in the spell description box However when I use it I get a conflict and it seems to conflict with 5th Edition OGL by Roll20 Companion and I get this Is there a different way to attach a sound a spell attack or will I have to use a separate soundboard option to play the sound?

It might be simpler and safer to put it in as an API Button: [Play Sound](!macro_code)

I have auto sounds on most of my players spells and attacks using the SimpleSound API. The simplest way for an attack is to make the attack/spell into a token action then add the simple sound macro e.g. %{-MBcaPEBx900av27BiVk|repeating_attack_-MSRldyGs2OvE1ffb4mu_attack} !splay arrowshot[[1d5]] If you use SmartAoE or spawn default token APIs to show spell area of effect you can piggyback the SimpleSound Macro when you spawn default token or SmartAoE has a play sound function included.
