.Map :: MoHAA Mapping

I'm rookie in script and I need help.
I made a map with a wall in the middle, I have put the actor with good entities and trigger with good entities, and i also put pathnode for spawning soldier. I made script then which looks:

exec global/ai.scr

level waittill prespawn

thread global/ai.scr::spawngroup #1 #1

Is it allright?
plx help me

Did you do every thing it says to do at the top of the global/ai.scr like nameing him enemyspawner and did you give him a set number and group number?
