% of Proc Spell's damage procs

[dpedroia15]

Ive been looking at spells like Ignite, Languish (Balance Druid T10 4P proc), etc, where a dummy spell is procced and the dummy spell does X% of the proccing spell's damage.

Most of the code is the same...

case <SPELLID>:
{
   basepoints[0] = int32(damage * triggerAmount/100);
   triggered_spell_id = <TRIGGERED_SPELLID>;
   break;
}

The problem I'm getting is that a lot of these spells aren't even proccing, even though I have tem under the correct Handler and correct Spell Family. I've tried debugging but I'm still too new at it to find the exact place where this is going wrong.

Could someone point me in the right direction?
