AFAIK, timer names can be the same as long as they are in seperate files. The scripts run independently.
The timers definitely don't loop like you mentioned. You might want to add a quest::stoptimer("spar1"); in there before you start it again. Other than that, it looks ok. I think the issue may be with $anivar1, since I have never used that variable. If you want to test the timers to make sure they are working properly, just replace:
Code:
my $anivar1 = quest::ChooseRandom(1, 5, 6, 7, 11, 30, 45, 46, 47);
quest::doanim($anivar1);
with:
Code:
quest::say("I'm saying it now and I will say it again in 6 seconds!");
