annoying, the main reason I didnt want to upgrade the commandset, was in case I had multiple things of a similar nature I wanted to do that were not mutually exclusive.
For example, what if you had an upgrade to change the combat cycle into a demo cycle, and an upgrade to make the battlebus come with 2 rocket men? you couldnt check which were purchased or if both were, so you couldnt upgrade the commandset accurately, I guess ill take a few more looks at odds and sods and see if I can hack a way around it, if not I might add another building.
Thanks a lot for all the help, shame it seems to be impossible, ill let you know if I do find a way but I doubt I will, I might also ask a question about a general ability im trying to add if you dont mind, I tried folowing a tutorial from "Slee" but I couldnt quite get it to do exactly what I wanted

.
Thanks again
