Fixed. Vhex, I confirmed your findings as I don't get the trigger line either. I suspect he is using a modified version too. I added this line to the beginning of AttackPost to extract the info from the "currentPowerInfo" JSON:
... and this one to the beginning of the "[r,if(isPC()),CODE:" block near the end:
[r:if(trigger != "--none--" && trigger != 0, "<b>Trigger</b>: "+trigger+"<br>", "")]
In his modified version, I am guessing the programmer just copied and pasted the "[r:if(alwaysEff != "--none--" && alwaysEff != 0, "<b>Effect</b>: "+alwaysEff+"<br>", "")]" line but only changed the "<b>Effect</b>" part.
PS: Yes, I said I would never touch Rumble's code. Deadolus, consider this a favor for old time's sake. I leave further modifications in the capable hands of LongShot and others.
