Dear Simon, I have stored all information at the link:
http://scsys.co.uk:8002/33309?hl=on&submit=Format+it! I have the same problem if I do s(PC1) + ..... + s(PC10) or s(Pc1,PC2,PC3,PC4,PC5)+s(PC6,PC7,PC8,PC9,PC10) or s(PC1,PC2,PC3,PC6,PC7,PC8) ..... I have renamed PC1.1,PC2.1,PC3.1,PC4.1,PC5.1 to PC6,PC7,PC8,PC9,PC10 for simplicity.
