Need to refresh the UI before non-nil value is returned

[PARRYHOTTEr]

Hello everyone!

I'm very new to coding addOns to wow, and i've encountered a problem that annoys me.

Whenever i launch the game, GetAverageItemlevel() returns a nil value. If i then reload the UI it will then start to return the expected values.

What i wish to figure out is a way to stop this behaviour of where i have to reload the UI once before the addOn displays the expected value.

The following code is giving me this problem:

local ilvlText = frame:CreateFontString(nil, "ARTWORK", "GameFontHighlight")
ilvlText:SetPoint("TOPLEFT", 10, -60)
local avgItemLevel, avgItemLevelEquipped, avgItemLevelPVP = GetAverageItemLevel()
ilvlText:SetText("Average equipped ilvl is: " .. tostring(avgItemLevelEquipped or "Refresh UI"))
