First of all thx for the hughe explanation BUT .. when i get here ..

Resize the Repeater Region so it covers the entire portion you'd like to be able to click.
Is that in the window of my tank then ?
I have the option to config slot nr 1 or 2 or no healer ect but when i drag ik to my healbot frame and i click .. nothing happens .. my tank casts a heal spell but my priest does nothing .
I use healbot btw . When i click left he should flash heal .. but does nothing .
