Small custom effect help

[Ohbalgruuf]

Hey Starfinders, wasn't sure if i should put this in the effect list post as its a custom one I am making, but still figuring out making custom effects and was just wondering what I have written wrong here:

Song of Thaal'drith (Will; SAVE: -2,)

[Zacchaeus]

Try SAVE: -2, will

[Ohbalgruuf]

Excellent that worked thank you so much! Ended up looking this for it to work:

Song of Thaal'drith; SAVE: -2, will

apparently will has to be lower case and does not like brackets
