I need iscript help

[Whiplash!]

I've tried but I can't understand iscript fundamentals. I would like to use a few custom grps in my campaign, but iscript prevents me from doing so. If anyone knows how to work it could they please help me?

btw campaign is pretty much done, its being beta tested as of now.

If the custom grps have the same number of frames and the same animations as the unit you're replacing, AFAIK you can use that unit's iscript code (copy the iscript start point in the images.dat settings to your new unit's image settings) unless you want to use a different shadow underlay from that unit.
