GetLevelOrChampionPointsString() API call

[VulcanTourist]

I needed a means to obtain the character level and CPs, and I rummaged about in the esoui.com wiki and found this:

GetLevelOrChampionPointsString(level, championPoints, iconSize)

That is the limit of the documentation about it. When I tried to use it, however, the result wasn't what I'd hoped.

Does anyone have more complete documentation about that API function, or know that it doesn't do what I hoped and there is a different one(s) that I should be using? Could it be a data typing issue? I know nothing of how data is typed in LUA or whether it's auto-type-converted as needed.
