Lots of problems here:

-This script will only run once: if you want it to run continuously you need to add a loop.

-You have 2 event monitors but no
Code:
end_monitor
statements.

-You must declare a counter for
Code:
Acrebesieged
.

-You don't have an
Code:
end_if
for
Code:
if I_CompareCounter Acrebesieged = 0
.

I'd suggest you simplify the script drastically, get it to work, and slowly add complexity.
