Hello,

I am trying to get my alert frame (for achievements, etc) on top and reverse the grow order. Normally they get put on top of each other.

Since I don't find any small addon which does that or is out of date I was looking into ElvUI, since I know there is some code like that. I kinda get it to work w/o having all of ElvUI stuff in my UI, since I don't need it.

Now to my problem: somehow it kinda works but throwing out a lot of erros .. maybe someone can help me to figure out what exactly is wrong.
