HI tysm for your response.
I had tried the things you suggested many times over but still the same problem. The linked sets rezzed but there would always be one or two out of place. I tried to rez above my sim in the center at first but to no avail, then I moved it to the center of my homestead which is completley empty and tried there. No luck again. after 3 hrs of wracking my brains I moved to my friends sim & still no joy lol and then back to my homestead. The build consists of 5 different linked condo's. I realised that the root prim on each linked part was furthest from the rez box, so moved the scripts closer in each linked set and voila! I literally almost fainted ! It seems the further the scripts are from each other the more they mess up Pfft in future i may just stick to building sheds lol . Thank again for your help !
