Hello I would like some help fixing lua errors on a WA

[turbid fiber]

Hello, not very good at this stuff, so I took 2 weakauras and turned them into a weakaura that I wanted for tracking priest buffs and ranks, and need some help cleaning up lua errors.

you basically just need to change it from
spellId = aura_env.state.spellId
to
local spellId = aura_env.state.spellId
same for rank

reason for the error is if you don't do that then spellId becomes a global value, where all of your other weakauras check it too. can cause problems sometimes

thank you ill take a look after ❤️

Is it cool if I post a bugstack error I'm getting with the weakaura? I changed the rank and spell ID to local, I believe correctly?

yes post any bugsack errors you get, and also link the updated aura if you can

function()
local spellId = aura_env.state.spellId
if spellId == nil then return end
local rank = string.match(GetSpellSubtext(spellId), "%d+")
return rank
end

[fathom echo]

switch to:

function()
    local spellId = aura_env.state.spellId
    if spellId then
        local rank = GetSpellSubtext(spellId)
        if rank then
            return rank:match("%d+")
        end
    end
end

error happens because GetSpellSubtext sometimes doesn't give anything when spell data isn't loaded yet
