Thank you for your time Meaglyn, though I still can't get it to work. I'll just list what I've done to try and make it take effect in a custom module of mine and if you've got the time to read this and reply I'd greatly appreciate it.
Basicaly I load up the script nw_ch_summon_9 in the script editior, press ok to use script edition as module exclusive. Then I have tried pasting the code Shadooow showed into various parts of the script, inside the void main() and outside to no effect ingame when I run the module.
If that is enough detail, am I missing an obvious step or is this just a strange thing not to work??
