Two constant gearswap errors

I cannot figure out what the issue is but I'm receiving this error repeatedly...

Error 1

> GearSwap: Lua error (runtime) - ...gram Files (x86)/Windower4//addons/GearSwap/flow.lua:288: 
> GearSwap has detected an error in the user function pretarget:
> ...(x86)\Windower4\/addons/GearSwap/data/Player_THF.lua:298: attempt to compare number with nil

This is line 298

elseif (spell.english == 'Ranged' and spell.target.distance > 24.0) or (spell.type == "WeaponSkill" and spell.target.distance > target_distance and player.status == 'Engaged') then

The full function of 298 is

function pretarget(spell,action)
	if (spell.type:endswith('Magic') or spell.type == "Ninjutsu") and buffactive.silence then -- Auto Use Echo Drops If You Are Silenced --
		cancel_spell()
		send_command('input /item "Echo Drops" <me>')
	elseif spell.english == "Berserk" and buffactive.Berserk then -- Change Berserk To Aggressor If Berserk Is On --
		cancel_spell()
		send_command('Aggressor')
	elseif (spell.english == 'Ranged' and spell.target.distance > 24.0) or (spell.type == "WeaponSkill" and spell.target.distance > target_distance and player.status == 'Engaged') then -- Cancel Ranged Attack or WS If You Are Out Of Range --
		cancel_spell()
		add_to_chat(123, spell.name..' Canceled: [Out of Range]')
		return
	end
end

I think it's related to this at the beginning of the file but I'm not certain.

-- Set Default Distance Here --
target_distance = 6

Error 2

> GearSwap: Lua error (runtime) - ...gram Files (x86)/Windower4//addons/gearswap/flow.lua:288: 
> GearSwap has detected an error in the user function precast:
> ...(x86)\Windower4\/addons/gearswap/data/Player_THF.lua:575: attempt to call global 'find_player_in_alliance' (a nil value)

The function line 575 is "local target = find_player_in_alliance(spell.target.name)"

function refine_waltz(spell,action)
	if spell.type ~= 'Waltz' then
		return
	end

	if spell.name == "Healing Waltz" or spell.name == "Divine Waltz" or spell.name == "Divine Waltz II" then
		return
	end

	local newWaltz = spell.english
	local waltzID

	local missingHP

	if spell.target.type == "SELF" then
		missingHP = player.max_hp - player.hp
	elseif spell.target.isallymember then
		local target = find_player_in_alliance(spell.target.name)
		local est_max_hp = target.hp / (target.hpp/100)
		missingHP = math.floor(est_max_hp - target.hp)
	end

	if missingHP ~= nil then
		if player.sub_job == 'DNC' then
			if missingHP < 40 and spell.target.name == player.name then
				add_to_chat(123,'Full HP!')
				cancel_spell()
				return
			elseif missingHP < 150 then
				newWaltz = 'Curing Waltz'
				waltzID = 190
			elseif missingHP < 300 then
				newWaltz = 'Curing Waltz II'
				waltzID = 191
			else
				newWaltz = 'Curing Waltz III'
				waltzID = 192
			end
		else
			return
		end
	end

	local waltzTPCost = {['Curing Waltz'] = 20, ['Curing Waltz II'] = 35, ['Curing Waltz III'] = 50, ['Curing Waltz IV'] = 65, ['Curing Waltz V'] = 80}
	local tpCost = waltzTPCost[newWaltz]

	local downgrade

	if player.tp < tpCost and not buffactive.trance then

		if player.tp < 20 then
			add_to_chat(123, 'Insufficient TP ['..tostring(player.tp)..']. Cancelling.')
			cancel_spell()
			return
		elseif player.tp < 35 then
			newWaltz = 'Curing Waltz'
		elseif player.tp < 50 then
			newWaltz = 'Curing Waltz II'
		elseif player.tp < 65 then
			newWaltz = 'Curing Waltz III'
		elseif player.tp < 80 then
			newWaltz = 'Curing Waltz IV'
		end

		downgrade = 'Insufficient TP ['..tostring(player.tp)..']. Downgrading to '..newWaltz..'.'
	end

	if newWaltz ~= spell.english then
		send_command('@input /ja "'..newWaltz..'" '..tostring(spell.target.raw))
		if downgrade then
			add_to_chat(158, downgrade)
		end
		cancel_spell()
		return
	end

	if missingHP > 0 then
		add_to_chat(158,'Trying to cure '..tostring(missingHP)..' HP using '..newWaltz..'.')
	end
end

Any help with this would be appreciated. It's getting to be very annoying seeing these errors so often in console log. Is it better to just remove the function pretarget(spell,action) and waltz altogether being a THF?

Thanks for your time and help

For error 1, you can try spell.target.distance > 6 instead of spell.target.distance > target_distance, you do not need the variable target_distance if the value is constant.

For error 2, probably the function find_player_in_alliance is not defined in your lua. Check where you copy the code from and search for find_player_in_alliance.

Thank you problem resolved
