Making frame appear in combat. Hide out of combat.

[SRCarebear]

I'm working on an edit of sFilter to track all general debuffs on the target. I renamed it to aFilter as I still use sFilter for personal buffs. I'm a little stuck though in trying to make the frame appear when I am only in combat.

I have attempted to add some code to hide the frame out of combat and pop up for when I'm in combat but it only pops up for a second and then disappears again instantly.

I added

frame:RegisterEvent("PLAYER_REGEN_ENABLED")
frame:RegisterEvent("PLAYER_REGEN_DISABLED")

to the function, and also added

			
if event == "PLAYER_REGEN_DISABLED" then
self:Show()
else
self:Hide() 
end
end)

How do I make it appear for the whole duration of combat, and not just when I get into combat?
