Lone Wolf Development Forums - Bloodline ability replacement blood piercing

Hopefully an easy one. I've got a Sorcerer/Dragon Disciple character, and I'm trying to replace the 9th level bloodline power (Breath Weapon) with blood piercing, but probably because it only expects one option, it picks the wrong one (Dragon Resistances)

The script is:

Code:

~ This ability replaces the sorcerer’s 9th-level bloodline power

        field[usrArray].arraytext[0] = "Sorcerer Bloodline Power (9th)"



        perform assign[AbReplace.cSorBl9th]



        call SorBlAbRep

How can I get it to swap out dragon breath instead? Thanks!
