Lua Heal Party -> Heal Friend

[dangerangel2140]

Is there a way to turn the heal party spell (utura mas sio) into a single target heal friend type spell?

I tried removing

local membersList = getPartyMembers(cid)
	if(membersList == nil or type(membersList) ~= 'table' or table.maxn(membersList) <= 1) then
		doPlayerSendCancel(cid, "No party members in range.")
		doSendMagicEffect(pos, CONST_ME_POFF)
		return LUA_ERROR
	end

	local affectedList = {}
	for _, pid in ipairs(membersList) do
		if(getDistanceBetween(getCreaturePosition(pid), pos) <= 36) then
			table.insert(affectedList, pid)
		end
	end

	local tmp = table.maxn(affectedList)
	if(tmp <= 1) then
		doPlayerSendCancel(cid, "No party members in range.")
		doSendMagicEffect(pos, CONST_ME_POFF)
		return LUA_ERROR
	end

from the data/spells/scripts/party/heal.lua
But when I do that it pretty much does nothing, doesn't show the words of the spell cast but doesn't give an error or a "You don't have enough mana" or "No party members in range." type message either. Any ideas?
