Does anyone now how to fix it?
Edit: I found out that the problem has to do with the ability Liquid Voice. When I add the script for it it shows that error, but by removing it the game works perfectly. But I want the ability to work, I don't want to just remove it.

On that line you're calling hasWorkingAbility without passing which ability you want to check for?

As for making Liquid Voice functional, hit CTRL + Shift + F and find this line in base 17.2.

  def pbModifyType(type,attacker,opponent)
	if type>=0
	  if attacker.hasWorkingAbility(:NORMALIZE) && hasConst?(PBTypes,:NORMAL)
		type=getConst(PBTypes,:NORMAL)

Then hit the enter button to start a fresh line and copy and paste the following.

	  elsif attacker.hasWorkingAbility(:LIQUIDVOICE) && isSoundBased?
		type=getConst(PBTypes,:WATER)

If any errors arise from the code, please tell me. :3c They haven't from what I've tested in a fresh copy of 17.2.

Okay, it works! Thank you very much!
