Trying my 1st addon - a few basic questions

[vsrs_au]

Hi, I hope this is the right subforum for my thread, if not can the mods please move it?

I just started playing around with Baertram's FooAddon (from the "New to AddOn creation? - Usefull links and information" thread) to start learning about ESOUI addons, and have a few questions:

- I specified the ESOUI API version as 101039 in the addon, because https://wiki.esoui.com/APIVersion says that's what it should be, but in the addons menu in the game it's flagged as out of date, why is that?

- FooAddonIndicator:ClearAnchors() gives exception 'attempt to index a nil value'. Any ideas on what I've done wrong here? I wrote the addon as specified in that tutorial page, and it worked up to the point where I added the saved variables code and the code to move the indicator icon, but now gives the exception every time the addon is [re]initialised.
