Ok, try this one:
1. delete from the second behaviour:
if selected = true
switch to frame 0 for self
if selected = false
switch to frame 1 for self
set selected to selected?
set selected to selected?
2. add to the first behaviour:
when troops enters region
switch animation to frame 1
when troops exits region
switch animation to frame 0
if it doesn't work, then you can upload your test file to the forge and I'll try to modify it for you.
