TellMeWhen - Strata/Framelevel

[zoktar]

As the title suggests, im having difficulty with strata and framelevels regarding tmw. Theres a place in group settings/position that lets you change Relative To, that currently says UIParent. Im thinking thats the strata right?. And on bottom theres a Frame Level selector from 1-100. So thats the sublevel right?.

It doesnt seem to recognize any other strata lines like BACKGROUND, LOW etc
